Ablock of mass 2.0kg resting on a smooth horizontal plane is acted upon simultaneously by two forces, 10n due to north and 10n due to east. the magnitude of the acceleration produced by the forces on the block is what

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:
