Suppose you want to place a weather satellite with mass m into a circular orbit of altitude RE/10, where RE is the radius of the earth. PS: Give your answers in terms of the parameter = (GME)/RE with G and ME universal gravitational constant and the earth's mass respectively (take the potential energy to be zero at infinite distance). 1. What is the speed of the satellite in this orbit? 20A 10X (a) (b) 20 (c) 21 (d) 210X (e) 11 . What is the radial acceleration of the satellite in this orbit? A (a) RE (b) (119) RE 10 2 A (c) 100- (d) 400- (e) RE RE 21 ( 100 ) . 2 X RE . What is the total mechanical energy of the satellite when it is in this orbit? (a) -5Am (b) - 20 11 5 5 -Am (c) + Am (d) +Am (e) - -xm 11 . How much work has to be done to place this satellite in this orbit? 41 6 (a) 11Am (b) -Am (c) -Am (d) 2m (e) 10Am 11 11
