Reference no: EM13495470

Kevin has a mass of 94.0 kg and is skating with in-line skates. He sees his 28.50 kg younger brother up ahead standing on the sidewalk, with his back turned. Coming up from behind, he grabs his brother and rolls off at a speed of 2.17 m/s. Ignoring friction, find Kevin's speed just before he grabbed his brother.
