Question

Greg runs across the front of the classroom with a momentum of 300 kg·m/s and jumps onto a giant skateboard. The skateboard is initially at rest and has a mass equal to Greg's. If we ignore friction with the floor, what is the total momentum of Greg and the skateboard?

Step 1

Given that Greg's momentum is 300 kg·m/s, we can write this as: Momentum of Greg = mass of Greg x velocity of Greg 300 kg·m/s = mass of Greg x velocity of Greg Since we are given that the mass of the skateboard is equal to Greg's mass, we can write: 300 kg·m/s = Show more…
