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 123 kg, including his armor, hurled himself against a 833 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started moving at 1.71 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. speed before: m/s speed after: m/s *By the way, this brief bio of Nate the Skate is written in the past tense, because not long ago he forgot to put on his Bounce- Tex before colliding with the Washington Monument in a perfectly inelastic collision. We will miss him.
