1. (a) 35800 km and 22240 mi. (b) 3070 m/s and 10090 ft/s.
2. (a) 6.67 m/s. (b) 0.0755.
I have the answers to the questions. I need help with understanding the steps it takes to get to the solution.
1. Communication satellites are placed in a geosynchronous orbit, i. e., in a circular orbit such that they complete one full revolution about the earth in one sidereal day (23.934 h), and thus appear stationary with respect to the ground. Determine (a) the altitude of these satellites above the surface of the earth, (b) the velocity with which they describe their orbit. Give the answers in both SI and U. S. customary units.
2. A hockey player hits a puck so that it comes to rest in 9s after sliding 30 m on the ice. Determine (a) the initial velocity of the puck, (b) the coefficient of friction between the puck and the ice.
