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

An object has an x-momentum of 8.5 kilogram-meters/second and a -momentum of 9.8 kilogram meters/second. What Is resultänt
momentum of the object?
OA 15.5 kilogram-meters/second
OB. 14.8 kilogram-meters/second
0c 12.97 kilogram-meters/second
OD. 16.8 kilogram-meters/second

Answers

Answer:

The resultant momentum is 12.97 kg.m/s. Choice: c

Explanation:

Momentum

The momentum is a vector that measures the quantity of motion that an object has. It's also known by the term "mass in motion".

As a vector, it can be expressed by its rectangular components:

[tex]\vec p = p_x\mathbf{i}+p_y\mathbf{j}[/tex]

The magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{p_x^2+p_y^2}[/tex]

The object described has an x-component of:

px=8.5 Kg.m/s

And a y-component of:

py=9.8 Kg.m/s

Thus, the magnitude of the momentum is:

[tex]\mid \mid \vec p \mid \mid =\sqrt{8.5^2+9.8^2}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{72.25+96.04}[/tex]

[tex]\mid \mid \vec p \mid \mid =\sqrt{168.29}[/tex]

[tex]\mid \mid \vec p \mid \mid =12.97[/tex]

The resultant momentum is 12.97 kg.m/s. Choice: c

A 50 kg object is accelerating to the right at 5 m/s2. What is the net force acting on the object?

Explanation:

The force acting on an object given it's mass and acceleration can be found by using the formula

force = mass × acceleration

From the question we have

force = 50 × 5

We have the final answer as

250 N

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.

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

Answers

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

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.

Calculate the force used if 108J of work done is moving a wrapped present 9M

Answers

Answer:

F = 12 N

Explanation:

Mechanical Work

Mechanical work is the amount of energy transferred by a force. It's a scalar quantity, with SI units of joules.

Being F the force vector and s the displacement vector, the work is calculated as:

W = F.s

If both the force and displacement are parallel, then we can use the equivalent scalar formula:

W=F.s

When the value of the work is known and we need to find the force, we solve the above equation for F:

[tex]\displaystyle F=\frac{W}{s}[/tex]

The wrapping present is moved by s=9 m doing W=108 J of work. The force used is:

[tex]\displaystyle F=\frac{108}{9}[/tex]

F = 12 N

An 80.0 kg fisherman jumps into a 37.5kg boat that is at rest. If the velocity of the fisherman is 5.60m/s when he jumps from the dock, what will be the velocity of the boat and fisherman after he lands in the boat?

Answers

Answer:

The velocity of the boat and fisherman after he lands in the boat is 3.812m/s

Explanation:

We will solve this question on the general Derivation for general case of a man jumping n the boat

m = Mass of the man = 80kg

M= mass of the boat 37.5kg

V(m, g) = Velocity of man with respect to ground = 5.6m/s

V(b , g) = Velocity of boat with respect to ground = Vo = 0m/s ( rest)

velocity of the boat and fisherman after he lands in the boat = V1

As there is no external force acting on the man then we can apply conservation of the Linear Momentum.

m*V(m, g) + M*Vo = (M+m)V1

[tex]V1 = \frac{ m*V(m, g) + M*Vo}{M+m}[/tex]

 On substituting the values we get

V1 = [tex]\frac{80*5.6 + 37.5*0}{80+ 37.5}[/tex]

V1    = [tex]\frac{448}{117.5}[/tex] = 3.812 m/s

Therefore the velocity of the boat and fisherman after he lands in the boat is 3.812m/s.
