A motor/hoist lifts a weight at B with the ideal pulley and rope system shown (*see attached). For the information given, the acceleration of B in ft/s[squared] is what?
*Please see attachment for diagram and please show your work.
Because, for motor,
Torque M = T*r
=> tension in the string T = M/r = ...
This solution is provided in 71 words and uses equations for torque and tension to calculate acceleration of the block. A .jpg diagram is attached to further understanding of the problem.
