Consider a motor that exerts a constant torque of 25.0 N⋅m to a horizontal platform whose moment of inertia is 50.0 kg⋅m2. Assume that the platform is initially at rest and the torque is applied for 12.0 rotations. Neglect friction.
Part A: How much work W does the motor do on the platform during this process?
W = 1885 J
Part B:
How long Δt does it take for the motor to do the work done on the platform calculated in Part A?
Thank you so much for your time :)
