Michael pushes on the handle of a 12-kg lawn mower. The force of friction between the mower and the grass is 9 N. The handle makes a 35° angle with the horizontal. Michael wants to accelerate the mower at a rate of 0.8m/s2. What force must he apply along the handle?

Amachinist turns the power on to a grinding wheel, at rest, at time t = 0 s. the wheel accelerates uniformly for 10 s and reaches the operating angular velocity of 96 rad/s. the wheel is run at that angular velocity for 40 s and then power is shut off. the wheel slows down uniformly at 1.5 rad/s2 until the wheel stops. in this situation, the time interval of deceleration is closest to:
