Problem

A ball of mass

160 \text{ g}

is thrown up at an angle of

60^\circ

to the horizontal at a speed of

10 \text{ ms}^{-1}

. The angular momentum of the ball at the highest point of the trajectory with respect to the point from which the ball is thrown is nearly (

g = 10 \text{ ms}^{-2}

). (1)
