# Rotational motion

At t=3s, a point on the rim of a .2m radius wheel has a tangential speed of 50m/s as the wheel slows down with a tangential acceleration of constant magnitude 10m/s^2.

a) What is the constant angular acceleration?

b) What is the angular velocities at t=3s & t=0s

c) Through what angle did the wheel turn between t=0s & t=3s?

d) At what time was the radial acceleration equal to g?

Please show me detailed algebra steps and formulas used.
