## Problem 6.10: A mass is lifted by a string

A 10-kg mass is attached via a massless string over a massless pulley to a hand (position is given in meters and time is given in seconds). The masses in each animation are identical. Restart.

1. Rank the animations according to the work done on the mass by gravity, from greatest to least.
2. Rank the animations according to the work done on the mass by the tension in the string, from greatest to least.
3. Rank the animations according to the total amount of work done on the mass, from greatest to least.

Indicate ties by placing the animation numbers in () please. For example, a suitable response could be: 1,2,(3,4),5,6.

1. Calculate the work done on the mass by gravity during each of the animations.
2. Calculate the work done on the mass by the tension in the string during each of the animations.
3. Calculate the total amount of work done on the mass during each of the animations.

Note: For this Problem, the mouse-down for coordinates has been disabled.
