Non-Uniform Motion

Non-Uniform Motion problem 8

A 200 g box is dragged with a spring balance on a horizontal rough surface so that it moves uniformly. The force shown by the spring balance is 0.3 N.

  • What is the frictional force?

  • If another box of the same mass is placed on the previous box, what is the force required for uniform motion now, and what is the friction force?
