Net Force — DirectionMediumQuestion 30230

Question

A block moves at constant speed along a rough horizontal surface. The net force on the block is:
  1. A
    Equal to kinetic friction
  2. B
    Equal to applied force
  3. C
    Zero
    Correct
  4. D
    Equal to mg

Correct answer

Zero

Explanation

Constant speed → zero acceleration → zero net force. Applied force exactly equals kinetic friction.
