Number i UnitsAn electric grinder is switched on at t = 0, accelerates uniformly for 15 s to its operating angular speed of 22 rad/s. The wheel then turns at constant angular speed for 35 s and is switched off, slowing uniformly at 3.5 rad/s² until it stops. From the time it is switched off, how long does the grinder take to stop turning? t = S Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary.3. A vacuum cleaner belt is looped over a shaft of radius 0.45 cm and a wheel of radius 1.80 cm. The arrangement of the belt, shaft, and wheel is similar to that of the chain and sprockets in figure. The motor turns the shaft at 60.0 rev/s and the moving belt turns the wheel, which in turn is connected by another shaft to the roller that beats the dirt out of the rug being vacuumed. Assume that the belt doesn't slip on either the shaft or the wheel. A. What is the speed of a point on the belt? B. What is the angular velocity of the wheel, in rad/s? Rear sprocket Front sprocket
