Day 35

This class period will be asynchonous. You don't have to join a discussion today. The conservation of energy homework is due at the end of our normal class period: 12:15. It is under Class Homework and is a quiz on Canvas. Here are the questions.

1. If a 3 kg ball is dropped from rest at a height of 5 m above the floor, how much kinetic energy will it have at the instant that it is at a height of 3 m? Assume that no heat or other energy is generated during the fall.

2. If a 1 kg ball is dropped from rest at a height of 4 m above the floor, how much kinetic energy will it have at the instant that it is at a height of 1 m when 0.5 J of heat is generated for every meter that the ball drops.

You should also be working the Webpages that are due on Friday (see Day 36).
