- 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.
