A Sliding Block Question

A Sliding Block Question

A wooden block is given an initial velocity up an incline plane. The block slides up the incline plane to some height and then slides back down the incline to the bottom. There is friction between the block and the incline plane. The question is, does it take the same time for the block to slide down the incline as it took to slide up the incline?

  • A. Yes, it's the same distance up and down, so the time up and down will be the same.
  • B. No, it takes more time to slide down the incline plane than it took to slide up.
  • C. No, it takes less time to slide down because gravity is helping the block slide down.
  • D. What exactly is an incline plane?
