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 119 kg, including his armor, hurled himself against a 869 kg stationary statue of Isaac Newton in a perfectly elastic linear collision. As a result, Isaac started moving at 1.85 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.
