Atorque of 12 n*m is applied to a solid uniform disk of radius 0.50 m. if the disk accelerates at 2.6 rad/s^2 what is the mass of the disk? a) 26 kg b) 25kg c) 17 kg d) 34 kg

mass = 36.92 kg

Explanation:

We have given the torque

Radius of the disk r = 0.50 m

Angular acceleration

We know that torque is given by here I is moment of inertia and is angular acceleration

So

Moment of inertia is given by

m = 36.92 kg

The given answer is not matched with this answer but after calculation i got m =36.92 kg

at positions a, g kinetic energy is maximum.

at position d, potential energy is maximum.
