(a) Calculate the angular acceleration.

(b) Calculate the time required to complete the 55 revolutions mentioned.

(c) Calculate the time required to attain the 7 rev/s angular speed.

(d) Calculate the number of revolutions from rest until the time the disk attained the 7 rev/s angular speed.

This is pretty straighforward. What is about it that you do not understand?

what equations do I use? thanks for your help.
