Mention some of the salient points about angular projection of projectiles.

If a particle of mass m is thrown with speed at an angle 60° with horizontal, then angular momentum of particle at highest point about point of projection is

If a particle of mass m is thrown with speed at an angle 60° with horizontal, then angular momentum of particle at highest point about point of projection is

Mention three salient features of Solanaceae.

A ball is projected with 20sqrt2 m//s at angle 45^(@) with horizontal.The angular velocity of the particle at highest point of its journey about point of projection is
