A circular plate with radius 0.5 m and mass 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 5 N sec, 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?

A.

87
