Question

A boy who exerts a 300-N force on the ice of a skating rink is pulled by his friend with a force of 75 N, causing the boy to accelerate across the ice. If drag and the friction from the ice apply a force of 5 N on the boy, what is the magnitude of the net force acting on him?(1 point) Responses 70 N 70 N 380 N 380 N 370 N 370 N 80 N

Answer 1

The magnitude of the net force acting on the boy can be found by subtracting the forces opposing his motion from the forces assisting his motion.

Net force = (300 N + 75 N) - 5 N
Net force = 375 N - 5 N
Net force = 370 N

Therefore, the magnitude of the net force acting on the boy is 370 N.
