Step-by-step explanation:
We have,
Mass of a bowling ball, m = 7.2 kg
Weight of the ball, W = 70.6 N
It is moving with a speed of 1 m/s
Force that the bowling ball applies on a pin is 15 N
It is required to find the force that the pin exerts on the bowling ball. It is a concept of Newton's third law of motion. The force that the ball applies on a pin is equal in magnitude with the force that the pin exerts on the bowling ball but in opposite direction.
Hence, the force that the pin exerts on the bowling ball is 15 N but in opposite direction.
