A man, using a 70 kg garden roller on a level surface exerts a force of 200 N at 45${^\circ}$ to the ground. What is the vertical force of the roller on the ground, if he pushed the roller? ($g = 10ms^{- 2}$)

Question

(d) Vertical force on the roller = weight of roller + component of force in vertical downward direction = ($70 	imes 10 + 200\ cos\ 45{^\circ}$)N
