Problem 7.5: A mass is lifted by a string
Animation 1 | Animation 2 | Animation 3 | Animation 4 | Animation 5 | Animation 6
Please wait for the animation to completely load.
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.
- Rank the animations according to the change in gravitational potential energy of the mass, from greatest to least.
- Rank the animations according to the work done on the mass by the tension in the string, from greatest to least.
- Rank the animations according to the change in kinetic energy of 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.
- Calculate the change in gravitational potential energy of the mass during each of the animations.
- Calculate the work done on the mass by the tension in the string during each of the animations.
- Calculate the change in kinetic energy of the mass during each of the animations.
