- Ultimate Byleth and Little Mac fight. Little Mac, who is a boxer, dashes forward at 26.6 m/s, fist first. Byleth moves in the opposite direction at 3.79 m/s, where they collide with Little Mac’s fist. After the punch Byleth flies backwards at 11.1 m/s. How fast, and in what direction, is Little Mac now moving? Little Mac has a mass of 48.5 kg and Byleth has a mass of 72.0 kg.arrow_forwardMake sure to draw a sketch with scale as wellarrow_forwardMake sure to draw a sketch with scale pleasearrow_forward
- Kirby jumps towards his enemy/ally, Meta Knight, at 2.06 m/s while Meta Knight glides in the opposite direction (toward Kirby) at 5.06 m/s. Kirby then begins to inhale, swallowing Meta Knight.
