An automobile engine propels a 1000 kg car (A) along a levelled road at a spedd of 36 km//h. Find the power if the opposing frictional force is 100 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.
