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 111 kg, including his armor, hurled himself against a 839 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started moving at 1.63 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. אח m/s speed before: speed after

mass of  skate(m1)  = 111kg let velocity before collision =  vi mass of  statue(m2) = 839kg velocity of statue after collision  = 1.63m/sec let the let velocity of skate  after collision =  vf using momentum conservation  =                                  {:[Longrightarrowm_(1)v_(i)=m_(1)v_(f)+m_(2)v_(2)],[Longrightarrow111(v_(i)-v_(f))=839 xx1.63],[Longrightarrowv_(i)-v_(f)=12.32]:} using energy conservation  =                      & ...
