Question

A ball is rolling across a field with a force of 20 N. If the force of friction from the field is 3.7 N, what would be the net force of the ball?

a. 16.3 N
b. 23.7 N
c. 20 N
d. 37 N

Answer 1

The net force on the ball is found by subtracting the force of friction from the applied force, resulting in 16.3 N.

Step-by-step explanation:

The net force on a ball rolling across a field can be calculated by subtracting the force of friction from the applied force. Since the ball is pushed with an applied force of 20 N and there is a frictional force of 3.7 N opposing the motion, the net force is the result of 20 N - 3.7 N. Therefore, the net force acting on the ball is 16.3 N, which corresponds to option a. 16.3 N.
