Turn in a hard-copy with your name on it to SRTC 134 by 12:45PM Version B A large disc-shaped grindstone is spinning at 500 revolutions/min. The grindstone has a mass 4.0 kg and radius 9.0 cm. The moment of inertia of a disc rotating about its center is given by I = MR² The power is shut off by the operator and to slow it down, she sharpens a 4 kg axe by holding it against the grindstone until it stops 7 s later. Assume the angular acceleration is constant while the grindstone is slowing down. (A) Draw a diagram…Please show all your work on the paper. Circle the final answer by pen.
