Question
UI-Constant Force moves along a straight line from the position z_0t0 the position z a constant. The force applied on the object is given by 3k, where k is F=F0 ( -1). Calculate the work done by this force while the object moves from z to .

Sum of the forces along the ramp = m*a = -m*g*sin(33)
a = -g*sin(33) = -5.34 m/s^2
vf^2 = vi^2 + 2*a*d
d = (vf^2 - vi^2) / (2*a)
2*a = -2*5.34 = - 10.68
vf = 0
vi^2 = (7.81)^2 = 60.99
d = -60.99 /-10.68 = 5.71 m
