What speed should a satellite with a mass of 1500 kg at 8,500 km above the center of the Earth be travelling at in order to
stay in orbit (remember, the mass of the Earth is 5.97 x 1024 kg)
(in m/s, G = 6.67 x 10-11 N (m/kg) 2).

Where is the potential energy throughout the loading, cocking, and releasing of the trebuchet?

16. a brave but inadequate rugby player is being pushed backward by an opposing player who is exerting a force of 800 n on him. the mass of the losing player plus equipment is 90.0 kg, and he is accelerating at 1.20m/s2 size 12{1 "." "20"" m/s" rsup { size 8{2} } } {} backward. (a) what is the force of friction between the losing player’s feet and the grass? (b) what force does the winning player exert on the ground to move forward if his mass plus equipment is 110 kg? (c) draw a sketch of the situation showing the system of interest used to solve each part. for this situation, draw a free-body diagram and write the net force equation.

Ajoint produces movement when its angle decreases. which type of movement is it?
