Question

Two superheroes from the Avengers squad, Ironman and Captain America, are trying to put Thor's hammer on a platform. Ironman, who can fly, thinks he can just pick the hammer up and place it on the platform. Believing he should save his energy (for the upcoming battle with Thanos), Captain America suggests Ironman should instead push it up a ramp. Assume the hammer has a mass of 5 kg. the ramp and platform have a height of 3m, and the ramp makes an angle with the horizontal of 0-30° h VS Part 1 A Draw a system schema with the hammer as the only thing in the system. B. If Ironman wants to do less work, should he pick it up or push it up a ramp, or does it not matter? Calculate the work in each case to justify your answer. Assume the hammer comes to rest when it reaches the platform
