Solution

The correct option is C Angle with horizontal is less at the time of striking the ground compared to angle of projection with horizontal
In normal conditions the horizontal velocity remains constant but in the condition of a air friction the horizontal velocity decreases as a result this decreases the angle of velocity making with ground
the ground
