Question

A carpenter lifts a 20kg piece of wood to his shoulder 1.5m above the ground. He then sets the wood on his truck at 1.0 m above the ground and makes his delivery going 10 m/s What is the wood's potential energy on the carpenter's shoulder? Show all work, the rubric is included for this problem.

Answer 1

10kg

Step-by-step explanation:

it is 10kg bc the energy is false kenetic. The greater mass a moving object has, the more kinetic energy it has it has has kinetic energy because of its position Friction causes some mechanical energy to change to thermal energy. Doubling an object's velocity will double its kinetic energy
