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

Answer

The force will be

$2.4 * 10^6 N$

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

$Force = 2.4 * 10^6 N$
