How fast must a 0.05kg golf ball strike a stationary 5.0kg bowling ball so that the bowling ball reaches a final velocity +10.0m/s, assuming the golf ball rebounds with 20% of its initial velocity in the opposite direction? Determine the initial velocity of the golf ball assuming the final velocity of the bowling ball is +10.0m/s, and the final velocity of the golf ball (vf g) is equal to -0.2vi g (mind the - sign). Please show your work.

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.
