choose the correct answer Mike, of mass m, drops from a tree limb at the same time that John, also of mass m, begins his descent down a frictionless slide. The slide is in the shape of a quadrant of a circle. If they both start at the same height above the ground, which of the following is true about their kinetic energies as they reach the ground? a) The kinetic energy of John is greater than that of Mike b) The kinetic energy of Mike is greater than that of John. c) They have the same kinetic energy. d) It is impossible to say from the information given
