Help please!! 

A particle moves around a circle of radius R. In moment t = 0 it was located in point O. After, its velocity changes according to Vτ = αt - βt2, where α and β - positive constants. Find the modulus of the total acceleration when particle will be in point O again.

A lift ascends from rest with uniform acceleration of 4m/s^2, then it moves with uniform velocity and finally comes to rest with uniform retardation of 4m/s^2. If the total distance covered during ascending is 28m and total time taken for ascending is 8s respectively. Find the time for which the lift moves with uniform velocity .Also find its uniform Velocity.
