At what point in its trajectory does a projectile have its (i) minimum speed (ii) maximum speed?

Answer:

                For a projectile given angular projection, the horizontal component of velocity remains constant through- out while the vertical component first decreases, becomes zero at the highest point and then increases again. Hence (i) Projectile has minimum speed at the highest point of its trajectory. (ii) Projectile has maximum speed at the point of projection and at the point where it returns to the horizontal plane of projection.
