Mass data: bricklayer 60 kg, bricklayer 60 kg, barrel full of bricks 250 kg, empty barrel 25 kg 5. The bricklayer has just cut the rope that runs up over the pulley and back down
to the loaded barrel. He begins to accelerate upward at a rate of 7.9 m/s/s.
Calculate the tension force 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.
