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 129 kg, including his armor, hurled himself against an 831 kg stationary statue of isaac newton in a perfectly elastic linear collision. as a result, isaac started moving at 1.29 m/s and nate bounced backward. what were nate's speeds immediately before and after the collision? ignore friction with the ground. choose the correct option;
(a) before collision: 4.8m/safter collision: 1.29m/s
(b) before collision: 2.8m/safter collision: 2.29m/s
(c) before collision: 3.8m/safter collision: 3.29m/s
(d) before collision: 5.8m/safter collision: 1.29m/s
