Question

a trolley of mass 40kg us pushed up a hill of height 10m at an angle of 20 degree. calculate the force required to reach this height. how do i complete this question?
m*g = 40kg * 9.8N/kg = 392 N. = Wt. of
trolley.

Fp = 392*sin20 = 134.1 N. = Force parallel to the hill.

F-Fp = m*a
F-134.1 = m*0 = 0
F = 134.1 N.
