A 20.0 kg crate is pushed across a rough floor for a distance of 90.0 cm. When the force pushing the block is equal to 80.0 N and applied at an angle of 18.0 below horizontal to the block, the block moves at a constant speed of 2.10 m/s. What is the net force on the object?

asked by Diana
  1. Since the speed is constant, which does that say about the NET force?

  2. Hint: You don't need any of the numbers you provided to answer that

  3. Since it's constant, the net force is 0?
