A torque of 70 N-m acts for 10s on a disk with moment of inertia 160kg*m^2. If the disk is originally stationary, what's final angular speed of the disk?

SUMMARY
A torque of 70 N-m applied for 10 seconds on a disk with a moment of inertia of 160 kg*m² results in a final angular speed that can be calculated using the equations of rotational dynamics. Specifically, the relationship between torque (τ), moment of inertia (I), and angular acceleration (α) is defined by τ = I * α. The angular speed (ω) can then be derived from the angular acceleration over the time period of 10 seconds. Refer to equations #7 and #8 from the provided link for detailed calculations.
