10. John has borrowed his parents car without permission and is driving without a license. He
sees them out walking and realizes that they will be home in about 45 seconds. He is 500 m
from home and driving 25 m/s. Will he get to the driveway before they do?

Answers

Yes

Explanation:
John is driving at 25 meters per second and he has to drive 500 meters to get to his house.
I divided 500 by 25 to see how long it would take for John to get to his house
- 500/25= 20

Therefore, it will take John 20 seconds to reach his driveway, which is 25 seconds less than how long it will take his parents- so he will get to the driveway before them.

What is chemical reaction?

A chemical reaction is a procedure that causes one group of chemical components to change chemically into another.

Chemical reactions, which can frequently be described by a chemical equation, traditionally include changes that only affect the locations of electrons in the formation and dissolution of chemical bonds between atoms, with no change to the nuclei (no change to the elements present).

The study of chemical processes involving unstable and radioactive elements, where both electronic and nuclear changes may take place, is known as nuclear chemistry.

When the teacher mixed zinc (Zn) with hydrogen chloride (HCl), chemical reaction happens and more than one new substances formed.

What is the momentum of A 200 kg shark swimming at 15 m/s

Answers

Answer:

3000 kg meter per sec

Explanation:

Momentum of an object refers the motion of an object. Momentum depends upon mass and velocity both.

Formula to calculate the momentum of any object is,

Momentum = Mass × Velocity

By substituting values of mass and velocity of the shark from the question,

Momentum of shark = 200 × 15

                                  = 3000 kg meter per second

Therefore, shark weighing 200 kg has the momentum as 3000 kg meter per seconds.

Why is it important to describe motion in universal terms?

Answers

Answer:

Motion requires force to cause that change. The time you take to travel the distance depends upon speed; the distance travelled is measured as the length of a line between the start and end of a motion. It is an important aspect in physics. In our lives motion is important and impacts so many things that we do.

Explanation:

The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

The motion of an object occurs when there is change in the position of the object with time and the object moves in the direction of the applied force. This motion is influenced by the net force acting on the object.

For example:

The dimension of speed of object in motion is measured with two fundamental quantities (length and time);

speed = LT⁻¹

The motion of every object is relative, thus it is important to discuss this motion in universal terms which serves as a reference point.

accelerate to a speed of 12 m/s?

3 sec
2 sec
4 sec
12 sec
None of the other answers

Answers

Given:-

Acceleration,a = 3 m/s²

Initial velocity,u = 0 m/s

Final velocity,v = 12 m/s

To be calculated:-

Calculate the time take by a car.

Solution:-

According to the first equation of motion:

v = u + at

★ Substituting the values in the above formula,we get:

⇒ 12 = 0 + 3 × t

⇒ 12 = 3t

⇒ 3t = 12

⇒ t = 12/3

⇒ t = 4 sec

We are given with some parameters used in Kinematics for determining the motion of an object.

Accleration = 3 m/s²Started from rest (Initial vel.) = 0 m/sFinal velocity = 12 m/s

We have to find the time taken by the car to attain the final velocity with the given accleration. By using 1st equation of motion which says:

v = u + at

Final velocity = Initial velocity + Accl. × Time taken

Plugging the values,

➝ 12 = 0 + 3(t)

➝ 3t = 12

➝ t = 4 s

So, the correct answer is Option C. And we are done...

Refer to the position time graph provided to answer questions #1 thru 5.
1. What is the instantaneous velocity of the object at 5 s?

2. What is the distance the object moves from 0 to 9 seconds?

3. What displacement did the object have between 2 s and 9 s?

4. What was the object's average velocity over the first 5 seconds?
5. How many times does the object change direction of travel? (time zero
does not count and standing still does not count as a direction change)

Answers

Answer:

Explanation:

1). To calculate the instantaneous velocity of the object, we will calculate the slope of the line CD.

  Since line CD is a straight line, therefore, slope = 0

  Hence instantaneous velocity = 0

2). Distance of the object when it moves from 0 to 9 seconds

    = Distance traveled from (A to B + B to C + C to D + D to E)

    = 3 + (3 + 0.5) + 0 + 0.5

    = 7 m

3). Displacement = Distance between initial and the final positions of the object

    = 3 - 0

    = 3 m

4). Average velocity = [tex]\frac{\text{Displacement}}{\text{Time}}[/tex]

                                 = [tex]\frac{0.5}{5}[/tex]

                                 = 0.1 m per sec

5). Direction changes have been seen at t = 2 sec and t = 4 sec.

   Hence object changed its direction of travel 2 times.

A ball is dropped from rest from a high window of a tall building and falls for 4 seconds. Neglecting air resistance, the final velocity of the ball is?

Answers

Answer:

The final velocity of the ball is 39.2 m/s.

Explanation:

Given that,

A ball is dropped from rest from a high window of a tall building.

Time = 4 sec

We need to calculate the final velocity of the ball

Using equation if motion

[tex]v=u+gt[/tex]

Where, v = final velocity

u = initial velocity

g = acceleration due to gravity

t = time

Put the value into the formula

[tex]v=0+9.8\times4[/tex]

[tex]v=39.2\ m/s[/tex]

Hence, The final velocity of the ball is 39.2 m/s.
