Question #1402

A 6 kg cart is pulled on a level surface at a constant velocity of 2 m/sec by a constant force of 10 N. What is the acceleration? What is the frictional force opposing the motion?

Expert's answer

If the speed is constant, the acceleration is equal to zero.

If the acceleration is absent, all the forces are balanced. So, the friction force is equal to 10 N.

If the acceleration is absent, all the forces are balanced. So, the friction force is equal to 10 N.
