A ball of mass 160 g is thrown up at an angle of 60° to the horizontal at a speed of 10 m . 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

Answer: (3)

Solution

At the highest point the velocity is horizontal, m/s, and the height is \frac{(10\sin60°)^2}{2g}$ =
