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.
Nielsen reported that in Q4 2012, US consumers spent an average of 4 hours and 39 minutes per day watching live TV, and an additional 25 minutes with DVR playback and 11 minutes with DVD playback. That adds up to 5 hours and 15 minutes spent with TV under eMarketerâs definitionâsignificantly higher than our figure.
