Chapter 8 - Potential Energy and Conservation of Energy - Questions: 8a

Answer

The block will slide a distance less than D.

Work Step by Step

If h decreases, that means the blocks starts with a lower potential energy. Lower potential energy means a lower kinetic energy and velocity when it starts to move. When the block comes into contact with the friction patch, it will be slowed down more quickly because its traveling slower.
