Q. An automobile engine propels a 1000 kg car A along a leveled road at a speed of

36 k m h^{- 1}

. The frictional force is 100 N. Suppose after traveling a distance of 200 m, this car collides with another stationary car B of the 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.

Q. 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.
