Computation M t = An electric grinder is switched on at t = 0, accelerates uniformly for 17 s to its operating angular speed of 34 rad/s. The wheel then turns at constant angular speed for 34 s and is switched off, slowing uniformly at 9.3 rad/s² until it stops. From the time it is switched off, how long does the grinder take to stop turning? S QL Record your numerical answer below, assuming three significant figures. Remember to include a "-" as necessary.

As shown in the figure below, wheel A has a radius of 10 cm and is attached by a belt to to wheel C which has a radius of 25 cm. The angular speed of wheel A is increased from rest at a constant rate of 1.1 rad/s2(α). Determine the the time needed for wheel C to reach an angular speed of 100 rev/min assuming the belt does not slip. The linear velocity of the belt must be the same so αArA=αCrC. The relationship between angular acceleration and angular speed is ω=αt. 2pi rad = 1 rev. Don't forget to convert to consistent units.
