A 56-cm-diameter wheel accelerates uniformly about its center from 140rpm to 340rpm in 4.1s
a) Determine the radial component of the linear acceleration of a point on the edge of the wheel 1.6s after it has started accelerating. Give answer in m/s2.
b) Determine the tangential component of the linear acceleration of a point on the edge of the wheel 1.6s after it has started accelerating. Give answer in m/s2.
