1. A car with a mass of 200Kg is moving at an initial velocity of 5 m/s. How much time it needed to become at rest considering the road has a friction force of 10 Newton? 5 m/s 5 ms I time - ? . 200 kg At rest ti frictionless

Answer:
t=m/s/kg
t=5m/s/200kg
t=40m/s
hope it helps
Note: please correct me if I'm wrong
