Homework Statement
The full metal wheel of radius 30 cm, 300 kg of mass moment of inertia I = 1/2 (mr ^ 2) operating torque 50nm in time 1 min. Determine the angular acceleration, angular speed of wheel, revolutions per second, revolutions that the wheel makes to achieve this speed, kinetic energy.
Homework Equations
ω = 2∏/T, s=1/2(αt^2), Ek=(Iω^2)/2, I = 1/2 (mr ^ 2)
The Attempt at a Solution
First I can get ω, T=60sec, so ω=∏/30...
So I can get all of this using those few formulas, but in the end I get kinetic energy in mJ??
