QQQ

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 skete, with a mass of 113kg, including his armor, hurled himself against a 801-kg stationary statue of lsaac Newton in a perfectly elastic liner collision. As a result, lsaac started moving at 1.99 m/s and nate bounced backward. What were nate's speeds immediately before and after the collision?(Enter positive numbers.)lgnore friction with the ground. Before: After: 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.

Explanation / Answer

conservation of momemntum
113*x = 801*1.99 -113*y

x = 801*1.99/113 - y

conservation of energy

113*x^2 = 801*1.99^2 +113*y^2

113*(801*1.99/113 - y)^2 = 801*1.99^2 +113*y^2

speed after = y=6.058 m/s

speed before = 801*1.99/113-6.058=8.048 m/s
