m. m A mass m, = 4.1 kg rests on a frictionless table and connected by a massless string over a massless pulley to another mass m, = 3 kg which hangs freely from the string. When released, the hanging mass falls a distance d = 0.83 m. 1) How much work is done by gravity on the two block system? 2) How much work is done by the normal force on m,? 3) What is the final speed of the two blocks? 4) How much work is done by tension on m,? 5) What is the tension in the string as the block falls? 6) The work done by tension on only m, is: O posítive zero negative

A force FY shown in the figure below acts on a particle moving along the y axis. Each unit in the y(m) axis is equal to 2.0m and each unit in the Fy (N) axis is equal to 3.0N. Determine the work done on the particle by this force as it moves from the following initial to final positions. A. From y=A to y=B B. From y=B to y=C C. From y=A to y=C.
