Anybody in here taking Physics class right now or in the past? Can you help me out...i have 4 more questions: 1) How much impulse stops a 50-kg carton sliding at 4 m/s when it meets a rough surface? Conservation of momentum: mv(befor) = mv(after) 2) If a Mack truck and Ford Escort have a head on collision, which vehicle will experience the greater force of impact? the greater impluse? the greater change in momentum? the greater deceleration? 3)When a stationary uranium nucleus undergoes fission, it breaks into two unequal chunks that fly apart. What can you conclude about the momenta of the chunks? what can you conclude about the speed of the chunks? 4) Judy (mass 40.0 kg) standing on slippery ice, catches her leaping dog, Atti (mass 15kg), moving horizontally at 3.0 m/s. What is the speed of judy and her dog after the catch?
