Homework Statement
A circular plate with radius 0.5 m and mas 5 kg is hung on the wall, fixed at a point that is 0.3 m above its center. The plate can freely rotate about the fixed point with no friction. A very short-duration impulse of 5Ns, along a direction that is tangential to the circumference of the circular plate, is applied at the bottom point of the plate. From energy conservation, what is the maximum angle of rotation (away from the equilibrium position) attained by the plate?

The Attempt at a Solution
Ip=1/2 0.52*5+5*0.32=1.075
1/2 mv2=1/2 Iω2
ω=2.16rad/s
How can I calculate the duration of the impulse?
