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 $imes$ 10² J, W_N = 0 J, W_F = 6.7 $imes$ 10² J

Answer

W_m = -6.7 $imes$ 10² J, W_N = 0 J, W_F = 1.5 $imes$ 10² J

Answer

W_m = 0 J, W_N = 1.9 $imes$ 10² J, W_F = 1.3 $imes$ 10² J

Answer

W_m = 1.6 $imes$ 10³ J, W_N = 1.9 $imes$ 10² J, W_F = 1.7 $imes$ 10² J
