A car crashes into a wall with an impulse of 40,000kg.m/s The collision took 2 seconds . How much force did the wall exert? 60,000 N 80,000 N 40,000 N 20,00 ON

Impulse is defined as the change in momentum of an object when a force is applied over a period of time. The formula for impulse is given by: Given that the impulse is and the time is , we can rearrange the formula to solve for the force: Substituting the given values: Therefore, the force exerted by the wall is .
