If a constant torque of 500 Nm turns a wheel of moment of inertia 100 kg-m^2 about an axis through its centre, find the angular velocity and the kinetic energy gained in 2 seconds,

If a constant torque of 500 Nm turns a wheel of moment of inertia 100

1.	If a constant torque of 500 Nm turns a wheel of moment of inertia 100 kg-m^2 about an axis through its centre, find the angular velocity and the kinetic energy gained in 2 seconds,
Answer» SOLUTION :`prop = tau//l = 500//100 = 5 "rads"^(-2), OMEGA = at = 10 "rads"^(-1), K.E =(1//2)Iomega^(2) = 500 J`
