A2,000-kg car traveling at 40 m/s hits a wall with a force of 40,000 n and comes to a stop. what was the impact time?

The impact time is equal to seconds

Explanation:

Given -

Force (F) N or

Mass(M) Kg

Initial Velocity (u)

Final Velocity (v)

Force exerted by any body is equal to the product of its mass and acceleration

Hence, mathematically it can be represented as

Substituting the given values, we get -

As per Newton's first law of motion,

in case of deceleration

Substituting the available values in above equation, we get -

seconds

The impact time is equal to seconds
