Question

A 20 kg crate is being pulled up a 20° incline with a constant velocity by a force F at an angle of 15° below the horizontal. Determine the work done by the weight (mg), normal force (F_{N}) and applied force (F) on the crate as it travels 10 m along the incline.

Accepted Answer

W_{m} = -6.7﻿×	imes×﻿$$10^{2} J$$, W_{N} = 0 J, W_{F} = 6.7﻿×	imes×﻿$$10^{2} J$$

Answer

W_{m} = -6.7﻿×	imes×﻿$$10^{2} J$$, W_{N} = 0 J, W_{F} = 1.5﻿×	imes×﻿$$10^{2} J$$

Answer

W_{m} = 0 J, W_{N} = 1.9﻿×	imes×﻿$$10^{2} J$$, W_{F} = 1.3﻿×	imes×﻿$$10^{2} J$$

Answer

W_{m} = 1.6﻿×	imes×﻿$$10^{3} J$$, W_{N} = 1.9﻿×	imes×﻿$$10^{2} J$$, W_{F} = 1.7﻿×	imes×﻿$$10^{2} J$$
