Question
A car is moving on a level road.If the driver turns off the engine of the car, the car's speed decreases gradually and ultimately it comes to a stop. A student says that two forces act on the car which brings it to a stop. What could these forces be? Which of these two forces contributes more to slow down and stop the car?

When a 1700kg car skids to a stop with initial speed 9m/s on a flat road, it takes about 12m to stop. Given that friction is the force allowing the car to decelerate, how much distance would the same car need to stop if it were initially moving at 15m/s?

Question 22 An automobile engine propels a 1000 kg car (A) along a leveled road at a speed of 36 kmph. Find the power if the opposing frictional force is 100 N. Now, suppose after travelling a distance of 200 m, this car collides with another stationary car (B) of same mass and comes to rest. Let its engine also stop at the same time. Now car (B) starts moving on the same level road without getting its engine started. Find the speed of the car (B) just after the collision.
