Slanted surfaces without friction: A system comprising blocks, a lightfrictionless pulley, a frictionless incline, and connecting ropes is shown in thefigure. The 9.0-kg block accelerates downward when the system is releasedfrom rest. Calculate the tension in the rope connecting the 6.0-kg block andthe 4.0-kg block. (42 N)

A person doing a chin-up weighs 700 N, exclusive of the arms. During the first 25.0 cm of the lift, each arm exerts an upward force of 355 N on the torso. If the upward movement starts from rest, what is the persons velocity at that point?

A block is given an initial velocity of 5.00 m/s up a frictionless incline of angle = 20.0 (Fig. P5.47). How far up the incline does the block slide before coining to rest?
A skydiver is at an altitude of 1520 m. After 10.0 seconds of free fall, he opens his parachute and finds that the air resistance, FD , is given by the formula FD=bv , where bis a constant and vis the velocity. If b=0.750 , and the mass of the skydiver is 82.0 kg, first set up differential equations for the velocity and the position, and then find: (a) the speed of the skydiver when the parachute opens, (b) the distance fallen before the parachute opens, (c) the terminal velocity after the parachute opens (find the limiting velocity), and (d) the time the skydiver is in the air after the parachute opens.

A light rope is attached to a block with mass 4.00 kg that restson a frictionless, horizontal surface. The horizontal rope passes overa frictionless, massless pulley, and a block with mass m is suspendedfrom the other end. When the blocks are released, the tension in therope is 15.0 N. Draw two free-body diagrams: one for each block.
