- In the movie Fast X, a 10100 kg round bomb is set rolling in Rome. The bomb gets up to 17.6 m/s. To try to stop the bomb, the protagonist Dom swings the counterweight of a crane, which has a mass of 354000 kg into the bomb at 3.61 m/s in the opposite direction. Directly after the collision the crane counterweight continues in the same direction it was going at 2.13 m/s. What is the velocity (magnitude and direction) of the bomb right after the collision?arrow_forwardDon't use aiarrow_forwardMake sure to draw a sketch with scale pleasearrow_forward

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_forward
