A car weighing 5000 N is traveling along a straight level road powered by a forward drive force of 500 N. The force of air resistance is 200 N, and rolling resistance is 100 N. The net force on the car is
A) zero.
B) 300 N backward.
C) 500 N forward.
D) 5000 N downward.
E) 200 N forward.

Question

Quizplus · Accepted Answer

The net force is calculated by subtracting the resistive forces (air resistance and rolling resistance) from the forward drive force: 500 N - 200 N - 100 N = 200 N forward.
