Answer 2

The torque acting on the body is 250 N-m.

We can use the formula for torque to solve this problem:

Torque = Moment of inertia x Angular acceleration

First, we need to calculate the angular acceleration of the body:

Angular acceleration = (Final angular velocity - Initial angular velocity) / Time taken

= (90 - 60) / 60

= $0.5 rad/s^2$

Now we can substitute the given values into the formula for torque:

Torque = Moment of inertia x Angular acceleration

$= 500 kg-m*0.5 rad/s^2$

= 250 N-m

Therefore, the torque acting on the body is 250 N-m.
