A circular platform of radius 3.6 m is uniformly accelerated from an angular velocity of 0.15 rad/s to 0.86 rad/s in 1.8 s.
a. What is the angular acceleration, α?
b. What is the tangential acceleration, at at the outer edge of the platform?
c. What is the centripetal acceleration, ac at the outer edge at t = 1.8s?
d. What is the total linear acceleration at the outer edge at t = 1.8s?
