A lawn roller is pushed across a lawn by a force of 119 N along the direction of the handle, which is 22.5° above the horizontal. If 65.7 W of power is developed for 90.0 s, what distance is the roller pushed?
65.7W = 65.7 Joules/s.
Work = 65.7J/s * 90s = 5913 Joules
Work = F*d = 5913 Joules.
119*cos22.5 * d = 5913
109.94d = 5913
d = 53.78 m.
