Question

1.A 1200 kg car drives at a constant speed of 14 m/s around a circular track (r=80.0m). What is the size of the net force acting on the car?​

Answer 1

Zero

Step-by-step explanation:

Since the car is moving at a constant speed of 14 m/s, the acceleration must be zero, and thus the net force must also be zero. Any object moving at a constant speed will have a net force of zero, regardless of mass, speed, direction, or track.
