Problem 4.9: Rank the accelerations and tensions
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 acceleration of the mass, from greatest to least (positive is up).
- Rank the animations according to the tension in the string, from greatest to least (positive is up).
Indicate ties by placing the animation numbers in () please. For example, a suitable response could be: 1,2,(3,4),5,6.
- Calculate the acceleration of the mass in each animation.
- Calculate the tension of the string in each animation.
