Abowling ball weighing 71.2 n is attached to the ceiling by a 3.60 m rope. the ball is pulled to one side and released; it then swings back and forth like a pendulum. as the rope swings through its lowest point, the speed of the bowling ball is measured at 3.90 m/s.

a. at that instant, find the magnitude of the acceleration of the bowling ball.
b. at that instant, find the direction of the acceleration of the bowling ball.
upward/downward/in the direction of motion
c. at that instant, find the tension in the rope.

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.
