If the radius of an abrasive stone is 0.24 m, and

angular acceleration = 3.2 rad/s²

angular velocity = 8.6rad/s

After 2.7 s and r=0.24m

calculate

a) Linear or tangential velocity of a point on the periphery.

b) tangential acceleration of a point on the periphery.

c) radial acceleration of a point on the periphery, at the end of 2.7s.

d) repeat for a point halfway between the center and the periphery, that is, at r=0.12m
