Chapter 8 - Potential Energy and Conservation of Energy - Questions: 4a

Answer

Hill 4 is the first hill that the block can't cross.

Work Step by Step

Potential Energy=mgh ---Before it is dropped, the block's total mechanical energy is potential energy. Its total mechanical energy can't increase so the max height that the block may travel is its starting height (3 meters). The 4th hill is the only hill that is taller than 3 meters so the block can't cross it.
