1. Do Now Heading: Conservation of Momentum
Pick up 2 worksheets from the front table
Turn in your homework to the homework bucket

2. Draw/Answer the following problem
Two skateboarders are holding hands while rolling down a hill with a velocity of 10 m/s.
What is their total momentum?
If their friend pushed them with a force of 50 N, how much power did he use?
If he applied that force for 5 seconds, how much work did their friend do?
M = 45 kg
M = 70 kg
