A thin circular coin of mass 5 g and radius 4/3 cm lies initially in the horizontal xy-plane. It is tossed vertically upward by an impulse √(π/2)×10⁻² N·s applied 2/3 cm from its centre. The coin spins about a diameter and moves along +z. By the time it returns to its initial height, it completes n rotations. Find n. Take g = 10 m s⁻².
