What is the horizontal acceleration of a ball that is launched horizontally with a velocity of 5.6 m/s? a )–9.8 m/s2 b )0 m/s2 c )5.6 m/s2 d 9.8 m/s2

Horizontal acceleration is 0 m/s²

Explanation:

When a ball is launched horizontally with some velocity, its motion is called as  projectile motion. The velocity in horizontal direction is constant and is equal to

And in vertical direction the velocity is equal to,

Since, the velocity is constant in horizontal direction so the rate of change of velocity i.e. acceleration is equal to zero. The vertical component of acceleration is equal to -g.

So, the correct option is (B) " 0 m/s² "
