Jessica is visiting a park with her mother. jessica sits on a swing. her mother pulls the swing to a height of 3 meters above the ground and lets it go. the image shows jessica at three positions on the swing. jessica‘s mass is 44 kilograms and the maximum velocity of the swing is 5 meters/second. what’s the energy she has at each position shown? ignore friction and air resistance. use g = 9.8 m/s2, pe = m × g × h, and ke = 0 joules ke = 550 joules pe = 862.4 joules
