Question
An object of mass 12kg is pushed 34m up a frictionless slope that is at an angle of 56^o to the horizon.
Determine both (a) the work on the object and (b) its change on gravitational potential energy.

M*g = 12*9.8 = 117.6 N. = Wt. of the object.
Fp = 117.6*sin56 = 97.5 N. = Force parallel to the slope.
a. Work = Fp*d = 97.5 * 34 = 3315 J.
Fp = 117.6*sin56 = 97.5 N. = Force parallel to the slope.
a. Work = Fp*d = 97.5 * 34 = 3315 J.
