Question

A car of mass 2000 kg is driven by a force of 40 KN for 5 seconds. how much does its speed change

Answer 1

Based on the given information, we can calculate the change in velocity of the car using the following formula:

Change in velocity = (Force x Time) / Mass

Substituting the given values, we get:Change in velocity = (40,000 N x 5 s) / 2000 kg

Change in velocity = 100 m/s

Therefore, the speed of the car changes by 100 m/s.
