IP A gardener mows a lawn with an old-fashioned push mower. Thehandle of the mower makes an angle of 36^\circ with the surface ofthe lawn.
A: If a 212-{\rm N} force is applied along the handle of the15-{\rm kg} mower, what is the normal force exerted by the lawn onthe mower?
Express your answer using two significant figures.
B: If the magnitude of the force applied to the handle of the moweris fixed, but the angle between the surface of the lawn and thehandle of the mower is increased, does the normal force exerted bythe lawn increase, decrease, or stay the same?
C: If the angle between the surface of the lawn and the handle ofthe mower stays the same, but the magnitude of the force applied tothe handle is decreased, does the normal force exerted by the lawnincrease, decrease, or stay the same?
