Given: mearth = 5.98 × 1024 kg rearth = 6.37 × 106 m a satellite of mass 884 kg is in a circular orbit at an altitude of 532 km above the earth’s surface. because of air friction, the satellite eventually is brought to the earth’s surface, it hits the earth with a velocity of 3 km/s. let the gravitational potential energy be zero at r = [infinity]. the universal gravitational constant g = 6.67259 × 10−11 n m2 /kg2 . what is the total energy of the satellite in orbit? answer in units of j pdf
