A satellite wishes to orbit the earth at a height of 100 km (approximately 60 miles) above the surface of the earth. Determine the speed, acceleration and orbital period of the satellite. (Given: M earth = 5.98 x 10 24 kg, R earth = 6.37 x 10 6 m).Like most problems in physics, this problem begins by identifying known and unknown information and selecting the appropriate equation capable of solving for the unknown.etermine the speed, acceleration and orbital period of the satellite.

According to a study done by the A.C. Nielsen Company, the average  American watches about 4 hours of TV a day. That is equal to about  28 hours per week.
Retirees spend more than half of their leisure time watching TV, averaging about four hours per day. Older people watch over an hour more TV daily than the overall population, which watches two-and-a-half hours each day.
