A disk rotates about its central axis starting from rest and accelerates with constant angular acceleration. At one time it isrotating at 9 rev/s. 50 revolutions later, its angular speed is19 rev/s.
a) Calculate the angular acceleration.
b) Calculate the time required to complete the 50 revolutions mentioned.
c) Calculate the time required to attain the 9 rev/s angular speed.
d) Calculate the number of revolutions from rest until the timethe disk attained the 9 rev/s angularspeed.
