A bowling ball weighing 71.2 N (16.0 lb) is attached to theceiling by a 3.80 m rope. The ball is pulled to one side and released; itthen swings back and forth as a pendulum. As the rope swings throughthe vertical, the speed of the bowling ball is 4.20 m/s. At this instant,what are (a) the acceleration of the bowling ball, in magnitude and direction,and (b) the tension in the rope?

Computation. Three objects are connected as in the figure with mд-7 kg, mB=6.43 kg, and mc-11.4 kg. The strings and frictionless pulleys have negligible masses, and the coefficients of friction between the block and the table are s-0.67 and u-0.151.

Two blocks of mass m1 = 3.0kg and m2 = 2.5kg are attached with a rope. The rope goes around several ideal pulleys. Two of the pulleys are attached directly to the ceiling (grey shaded region at the top) and will not move up or down. The lower pulley will move with block 1. Block 1 is free hanging and will move vertically. Block 2 rests on an inclined ramp at angle θ = 30°. The ramp is frictionless. Block 1 is observed to accelerate upwards. The experiment is done on earth, g = 9.8 m/s2 What is the tension in the long rope? by using variables only

Connected objects with inclined plane problem. Consider the figure where you have two boxes connected by a string over a pulley. The smooth (frictionless) ramp is inclined to a an angle of 35° with the flat ground, and the box on the ramp has a mass of 6.40 kg. The mass of the 6.4 kg hanging box is m = 3.05 kg. You don't need to consider significant figures in your answer, but don't round excessively partway through your calculations. 35° Find (a) the direction and (b) the magnitude of the hanging box's acceleration.
