The kinetic energy of amoving object equals half the product of itsmass and the square of its velocity. K = (1/2)mV^2 As a spaceship is fired into orbit, all three ofthese quantities vary. Suppose that the kineticenergy of a particular spaceship is increasingat a constant rate of 100,000 units per secondand that mass is decreasing at 20 kg/s becauseits rockets are consuming fuel. At what rate isthe spaceship’s velocity changing when itsmass is 5000 kg and it is traveling at 10 km/s?
