Answer:

1. A

2. B

3. A

4. D

5. ?

Explanation:

1. Momentum is defined as the product of mass and its velocity. Momentum is a vector quantity. it is generally written as,

p = mv

here, m is the mass of the object and v is the velocity of the object.

Thus, momentum is mass times its velocity.

2. The momentum is the mass in motion, so it is calculated as the mass times the velocity. It means that the equation to calculate the momentum is

p = mv

Where m is the mass and v is the velocity of the object.

So, the answer is b. p = mv

3. The momentum of an object can be calculated with the formula below:

Where p is the momentum, m is the mass and v is the velocity.

The mass of the bus is greater than the mass of the car.

So, if they have the same velocity, the momentum of the bus will be greater.

4. The momentum of an object is given by the formula below:

p = mv

Where p is the momentum, m is the mass and v is the velocity.

Therefore the correct option of the first part is d.

5. ?

Then, calculating the momentum with a mass of 0.255 kg and a velocity is 35 m/s, we have:

p = 0.255 ⋅ 35

p = 8.925 kg m/s

Can you please double check the equation's choices?
