[-/1 Points] DETAILS SERCP11 5.QQ.004. MY NOTES Bob, of mass m, drops from a tree limb at the same time that Esther, also of mass m, begins her descent down a frictionless slide. 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? O Esther's kinetic energy is greater than Bob's. The answer depends on the shape of the slide. They have the same kinetic energy. O Bob's kinetic energy is greater than Esther's. Need Help? Read it 2. [-/1 Points] DETAILS SERCP10 5.WU.001.
