Question
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 115 kg, including his armor, hurled himself against a
891 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started moving at 1.45 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.
