Using the picture above, which ball has the greatest potential energy?

Answers

Answer 1

Ball 4 because the higher the elevation is the greater the potential energy it has

Answer 2

Ball 1 has the greatest amount of potential energy inside it because it has the maximum height among all the balls shown in the graph.

What is Potential energy?

Potential energy is the stored energy which depends upon the relative position of various parts of a system. A spring has more potential energy when it is compressed or stretched due to external force.

Potential energy is not affected by the environment outside of the object or its system, such as the air or height. On the other hand, kinetic energy is the energy of an object or a system's particles in motion.

The potential energy of an object depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity and h is the height in meters.

The object 1 has maximum height hence, it has greatest potential energy.

You have a 100 N object with a normal force of 100 N. You apply a 50 N push to the right, but a friend is hiding on the other side of the object and is also pushing with a force of 60 N. What is the net force on the object?

Answers

Answer:

100.49N

Explanation:

First we must know that the normal force acts in the vertical direction;

The force required to push to the right and left acts in the horizontal direction;

Sum of force along the horizontal Fx = 50N - 60 N = -10N

Force along the vertical Fy = 100N

The net force on the object is calculated as;

F = √(Fx)² + (Fy)²

F = √(-10)² + (100)²

F = √100 + 10000

F = √10,100

F = 100.49N

Hence the net force on the object is 100.49N

You are in a plane, and hit a bird as your flying, how can this impact produce a large impulse, despite the plane being much bigger

Answers

It effects the balance of the plane, and slows it. Also you are likely moving faster than the bird, and it would be almost as if you are hitting a brick. However when it makes the plane impulse then it means the sudden loss of speed (even if it is a small bird) that is keeping the plane in the air causes the planes engines to struggle for a short amount of time, while it tries to recover the little amount of speed it has lost (the engines HAVE to regain full speed or the plane will turn to the ground, maybe not ALL the way but it still will lower the nose.

A 20 kg crate initially at rest on a horizontal floor requires a 80 N horizontal force to set it in motion. Find the coefficient of static friction between the crate and the floor.

Answers

Answer:

The coefficient of static friction between the crate and the floor is 0.41

Explanation:

Friction Force

When an object is moving and encounters friction in the air or rough surfaces, it loses acceleration and velocity because the friction force opposes motion.

The friction force when an object is moving on a horizontal surface is calculated by:

[tex]Fr=\mu N[/tex] [1]

Where [tex]\mu[/tex] is the coefficient of static or kinetics friction and N is the normal force.

If no forces other then the weight and the normal are acting upon the y-direction, then the weight and the normal are equal in magnitude:

N = W = m.g

The crate of m=20 Kg has a weight of:

W = 20*9.8

W = 196 N

The normal force is also N=196 N

We can find the coefficient of static friction by solving [1] for [tex]\mu[/tex]:

[tex]\displaystyle \mu=\frac{Fr}{N}[/tex]

The friction force is equal to the minimum force required to start moving the object on the floor, thus Fr=80 N and:

[tex]\displaystyle \mu=\frac{80}{196}[/tex]

[tex]\mu=0.41[/tex]

The coefficient of static friction between the crate and the floor is 0.41

There are three types of friction. ______________ friction occurs when an object is not moving. ______________ friction occurs when an object is moving against another surface. ______________ friction occurs in the case of wheels or other round objects. The amount of friction depends on two things.First, how ______________ the surfaces are; and second, how ______________ the object is. It is ______________ to keep an object moving than to start it moving. This is because static friction is ______________ than sliding friction.

Traxit, traxrunt anyone have a course hero account i can use too? plus i need help on this question Read the passage and answer the questions that follows :(1) We all want to succeed. Whether its in losing weight learning the guitar,speed reading, or starting our own business. For those of us who have triedand failed, success seems elusive. Why is it one person succeeds where anotherpersonal fails? First and foremost, I believe it is in their mindset. But secondly,I believe that successful people have developed certain habits, either naturallyor through research that the rest of us havent stumbled upon yet.(2) What is important to you? Finding your core values may seem a bit off-topicwhen it comes to success, but creating goals that are in line with your valuesis key to creating intrinsic motivation. Sit and reflect on what you value most.Pick a handful of things and actually write them down. Remind yourself ofyour values every day, and reflect on whether you are honoring those valuesthrough your work.(3) Choose one goal to start. Something large enough that will give you a sense ofaccomplishment, while aligning well with your core values. Focus is key here.The more focused you are on one goal, the higher chance you have of success.Set a date for success. Identify when your hope to achieve your goal. Keepit realistic, while not giving yourself too much time. By setting a time limit, youare making the process more real. Believe fully in your ability to achieve yourgoal. Visualize yourself having completed your goal in the exact time-frameyou have chosen, although finishing early is also acceptable. You dont needto consider the failures that will happen along the way. Success is inevitable.Others may think you will fail, dont let yourself be one of them!(4) Set up negative consequences for missing the deadline. Necessity is the motherof all invention. If you can manage to keep yourself intrinsically motivated,thats great. If not, this will help kick you into gear and keep your eye on theprize. Prioritize the tasks you have in front of you. Dont always do the mosturgent thing first. Pick the task thats the most important. Sometimes theseoverlap, which is nice. By always accomplishing whats most important, youare making clear progress toward your goal.(5) Push yourself. Go out of your comfort zone. This is the best way to learn, andthe best way to make progress quickly. If youre looking for new ideas, beingrisk averse will not help. This takes a lot of self-awareness. Try and beconscious of when you are holding yourself back out of fear. Push yourself tobe courageous, and take that next step. Failure is inevitable when you takerisks, which is what youll be doing if you want to succeed. By its very definition,the desire to succeed at something means you are risking failure. Many peopletend to give up far too early. Use failure. Treat it as a good thing, and marchon!(6) Take time every day to sit quietly and reflect on your values, goals, and progressmade so far. Where have you excelled, and where can you do better. Iseverything you are doing still lining up with your core values? Always look forways to improve. Never stop learning. Know what everyone else is doing,and what everyone else has done, and how they did it. Search wide forknowledge that might help you, and any inspiration that may do the same.Never think you have nothing to learn from others.(a) On the basis of your reading of the above passage, make notes on itsusing recognizable abbreviations (Min. 4) wherever necessary.
