A horizontal circular platform of radius 2.0m starts from rest and rotates with constant angular acceleration. The tangential acceleration of a point on its edge is measured to be 1.5ms−2.
a. (i) Find the angular acceleration of the platform.
b. (ii) How long will it take for the linear speed at the edge to reach 12ms−1?
c. (iii) Calculate the angular displacement of the platform, in radians, during this time.
