a bar of length l and uniform density is held horizontally against a wall by a
pivot at one end and a rope of tension t which pulls up and to the left
making an angle with the vertical wall. the rope is attached to the bar at
a distance i = l from the wall. a mass m is resting at the end of the bar.
if the bar has total mass 2.3kg, the mass m=2.0kg, and the rope makes an
angle of 32.6' with the wall, what is the magnitude of the force exerted on
the bar by the pivot |fpivot| answer in newtons (n).

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.
