A crate weighing 250 N is pulled up a 20° incline by a rope with a tension of 200 N. If the crate moves 5 m up the incline, what was the work done on the crate by the rope? (T remains constant throughout)

234.9 J

Explanation:

The total force acting on the rope are the downward weight of the crate and the upward tension acting on the string.

F = Wcos20 - Tcos20

F = 250cos20 - 200cos20

F = 46.98N

The total work done on the crate by the rope is:

W = F * d

W = 46.98 * 5

W = 234.9J

no simpler subs form complex ones. synthesise = make

the answer is ampere

the ampere is used to measure electricity. an ampere is a unit of electric current equal. a unit of measure for the flow of current in a circuit. one ampere is the amount of current flow provided when one volt of electrical pressure is applied against one ohm of resistance.
