Question

A 2,000-kg test car, traveling 60 m/s hits a brick wall. Using motion pictures, the time involved is determined to be 0.050 s. What is the magnitude of the force that the car exerts on the wall?

Answer 1

The force will be

`2.4 * 10^6 N`

Step-by-step explanation

As given in question

Mass= 2000 kg

Velocity= 60 m/s

Time = 0.05 sec

As we know

`Acceleration = Velocity/Time`

`Acceleration = 60 / 0.05`

`Acceleration = 1200 ms^(-2)`

For force we know that

`Force= Mass * Acceleration`

`Force= 2000 x 1200`

`Force = 2400000 N`

`Force = 2.4 * 10^6 N`

So, The answer is

`Force = 2.4 * 10^6 N`
