- D BES 026 Dynamics of Rigid Bodies Problem 2: In "The Avengers" movie, there was a scene where Iron Man and Thor fight each other. At the beginning of the fight, Thor throws his hammer at Iron Man, hitting him and throwing him slightly up into the air and against a small tree, which breaks. From the video, Iron Man is standing still when the hammer hits him. The distance between Thor and Iron Man is approximately 10 m, and the hammer takes about 1 s to reach Iron Man after Thor releases it. The tree is about 2 m behind Iron Man, which he hits in about 0.75 s. Also from the video, Iron Man's trajectory to the tree is very close to horizontal. Assuming Iron Man's total mass is 200 kg, determine the mass of Thor's hammer. DVNA MICarrow_forward1. You and Booboo are riding bumper cars. You and your car have 335 kg of mass and a top speed of 5.3 m/s, Booboo with hers has 180 kg of mass and a top speed of 6.8 m/s. All cars have enough rolling friction to move and enough static friction on the side of their wheels to turn without inhibiting forward motion whatsoever. As soon a collision occurs the cars immediately disengage drive and brakes so the collision occurs as elastically as possible if the ride is functioning properly. A second, malfunctioning maximum speed occurs when the ride malfunctions. The coefficient of kinetic friction between broken, crushed bumper cars and the ground is 0.3. It takes 2s to accelerate from rest to your maximum speed. How much force does the electric motor exert on you and your car in Newtons? Your car breaks down.
