Each of the 4 engines of a jet airliner delivers 100,000 hp of mechanical power to the airliner when the airliner is traveling at constant altitude at a constant speed of 550 mi/h. How much mechanical power (in hp) does each engine deliver at the same thrust when the airliner is at rest on the ground

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.
