A batsman hits a cricket ball high in the air. Neglecting air resistance, the ball's horizontal component of speed is constant because it:

Ais not acted upon by any forces
Bis not acted upon by gravitational sources
Cis not acted upon by any vertical forces
Dis not acted upon by any horizontal forces
Correct Answer

Solution

When a batsman hits a cricket ball in air , it follows the projectile motion . As there is no acceleration (so , no force ) in horizontal direction , therefore horizontal speed remains constant through the whole journey . Whereas vertical speed changes due to gravitational acceleration .
