At the same time that the first arrow is dropped, a
second arrow is shot from a height of 5 ft with an
initial vertical velocity of o ft/s, but a horizontal
velocity of 100 ft/s. when does the second arrow
hit the ground, assuming it does not hit anything
else first? ignore the effects of air resitance.

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.
