p Consider two identical objects released from rest high above E

p Consider two identical objects released from rest high above E the surface of Earth. (Neglect air resistance for this question.) ' In Case 1, the object is released from a height above the 5 surface of Earth equal to 1 Earth radius, and its kinetic ? energy just before it hits Earth is K1. ) In Case 2, the object is released from a height above the surface of Earth equal to 2 Earth radii, and its kinetic energy just before it hits Earth is K2. Compare the kinetic energy of the two objects just before they hit the surface of Earth. K2 = 4K1 K2 = 2K1 4 K = K 2 3 1 [(2 = 2K1
