# Throwing a Frisbee#

As a frisbee (a flying disk) is released, it is spun so that its angular velocity increases from 0 to 12 $$\pi \; \rm{rad/s}$$ in 0.05 $$\rm{s}$$.

## Part 1#

Find the angular acceleration of the frisbee assuming that it is constant over this time interval. Your answer should be a multiple of $$\pi$$.

Please enter in a numeric value in $$\pi\frac{\rm{rad}}{\rm{s^2}}$$.

## Part 2#

Assuming that the frisbee is a solid disk of mass $$m=$$ 0.213 $$\rm{kg}$$ and diameter $$d=$$ 0.412 $$\rm{m}$$, find the moment of inertia of the frisbee about its centre.

Please enter in a numeric value in $$\rm{kg \cdot m^2}$$.

## Part 3#

Find the net torque acting on the frisbee during this time interval.

Please enter in a numeric value in $$\rm{N \cdot m}$$.

## Part 4#

Explain what role you think spinning the frisbee has in the stable motion of the frisbee while it is in flight.
