What power must be applied to this object to accelerate it from rest to an angular speed of 2.7 rad/s in 5.2 s about the x axis?
P = W / t - torque * angular velocity
The Attempt at a Solution
P = [(0.5 m)*(7 kg)*(acceleration)] * 2.7 rad/s
I don't know how to find acceleration or if I am doing this wrong all together. The right answer is 1.3 W. I tried plugging it into the motion equation v = vo + at to get a, that gave me the wrong answer.
