Question 4 • Physical Science

A bowling ball has a mass of 7 point 2 kilograms and a weight of 70 point 6 cap n It moves down the bowling alley at 1 meter per second and strikes a pin with a force of 15 point 0 cap n What is the force that the pin exerts on the bowling ball?

Answer
A
85 point 6 cap n
B
7 point 2 cap n
C
70 point 6 cap n
D
15 point 0 cap n

Explanation

By Newton’s third law, when the bowling ball exerts a force on the pin, the pin exerts an equal-magnitude force in the opposite direction on the ball. The ball’s force on the pin is 15.0 N, so the pin’s force on the ball is also 15.0 N. The correct choice is 15.0 N.
