Object A is launched as projectile with initial speed v at an angle ̘ above the horizontal. Object B has exactly the same initial speed at exactly the same angle as object A but object B is sliding up a frictionless incline as shown in the figure. Object A has mass M and object B has mass 2M. During the subsequent motion, each object will reach a maximum height above the starting location. (i) At its maximum height, which object has the larger kinetic energy? Explain. (ii) Which object has the larger maximum height? Explain.
