Question
a wheel 0.45m in diameter starts from rest and rotates with uniform acceleration to 6000 radians per minute in a time of 4s.Find angular acceleration of the wheel and speed of a point on the rim at end of 4s =w/t

Vo = 0
V = 6,000rad/min = 6,000rad/60s = 100 rad/s.
a = (V-Vo)/t = (100-0)/4 = 25 rad/s^2
V = 6,000rad/min = 6,000rad/60s = 100 rad/s.
a = (V-Vo)/t = (100-0)/4 = 25 rad/s^2
