Formulate the answer of all part of the given question

Question- a hard drive is turned on from rest and accelerates to 5100rpm rpm in 5.14 s. The drive then maintains this rate of rotation for 164s at which point it is turned off and slows to a stop.

Part A- What is the angular acceleration of the drive when it is first turned on?

Part B- If the hard drive has an angular deceleration of 2.62rad/s² after it has been turned off, how long does it take from when it is turned off to come to a stop?

Part C- Through what total angle has the hard drive turned from the moment it turned on until it stops again?

Give your answer in detail.
