Wile E Coyote and Road Runner, with masses of 12.5 kg and 0.3 kg, are at having fun at the ice rink. a) Wile E Coyote moves towards Road Runner with a speed of 3.4 m/s while Road Runner is static at the center of the rink. What is the combined momentum of the two? b) They collide and stick together. What is their velocity after the collision? c) From rest, Wile E Coyote and Road Runner push off against each other and glide to opposite sides of the rink. Wile E Coyote reaches the edge, 10 m away from the original position, in 100 s. How long does it take Road Runner to travel 42 m in the opposite direction?
