Question

A bowling ball has a mass of 6 kg. What happens to its momentum when its speed increases from 2 m/s to 4 m/s?

A) The initial momentum is 6 kg*m/s, and the final momentum is 3 kg*m/s
B) The initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s
C) The initial momentum is 12 kg*m/s, and the final momentum is 3 kg*m/s
D) The inital momentum is 6 kg*m/s, and the final momentum is 12 kg*m/s

Answer 1

Momentum = (mass) x (speed)

Choice-B is the correct one.

Answer 2

B) The initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s

Step-by-step explanation:

The momentum of an object is given by the product between its mass (m) and its velocity (v):

`p=mv`

Let's apply this formula to calculate the initial momentum and final momentum of the ball:

- initial momentum:

`p_i = m v_i = (6 kg)(2 m/s)=12 kg m/s`

- Final momentum:

`p_f = m v_f = (6 kg)(4 m/s)=24 kg m/s`

So, the correct answer is

B) The initial momentum is 12 kg*m/s, and the final momentum is 24 kg*m/s
