Acar collides into a concrete wall going 25.0 m/s . it stops in 0.141 seconds and has a change in momentum of 39,400. what is the mass of the car?

Mass of the car is 1576 kg.

Explanation:

Let the mass of the car be kg.

Given:

Initial velocity of the car is,

As the car stops, final velocity of the car is,

Change in momentum is,

Now, we know that, momentum is given as the product of mass and velocity.

So, change in momentum is given as:

Therefore, the mass of the car is 1576 kg.

with 5 seconds, no, but over time if the police car stays at 65m/s ad the speeding car stays at 60, then obviously yes, but the answer to your question would be, no.

hope this : )
