Question

A car and a truck are moving next to each other on the highway. The truck has a mass of 910 kg and the car’s mass is 227 kg. IF their momentums are equal and the truck is moving at 18 m/s, what is the speed of the car?

Answer 1

the car must move with the speed

`v = 72.16 m/s`

Step-by-step explanation:

As we know that the momentum of the car and truck is same

so as per the formula of momentum we have

`P = mv`

so we have

`m_1v_1 = m_2v_2`

so we will have

`910 * 18 = 227 v`

`v = 72.16 m/s`

So the car must move with the speed

`v = 72.16 m/s`
