What is meant by projectile and trajectory?

At what point of trajectory an object thrown upward is the acceleration perpen-dicular to the velocity.

A projectile is projectile at an angle of 15^@ to te horizontal with speed v. if another projectile is rojected with the same speed, then at what angle with the horizontal it must be projected so as to have the same range.
