< Question 3 of 4
Nate the Skate was an avid physics student whose main non-physics interest in life was high-speed skateboarding. In
particular, Nate would often don a protective suit of Bounce-Tex, which he invented, and after working up a high speed on
his skateboard, would collide with some object. In this way, he got a gut feel for the physical properties of collisions and
succeeded in combining his two passions. On one occasion, the Skate, with a mass of 117 kg, including his armor, hurled
himself against a 825 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started
moving at 1.95 m/s and Nate bounced backward.
What were Nate's speeds immediately before and after the collision? (Enter positive numbers). Ignore friction with
the ground.
