Afootball is kicked with a velocity of 31 meters per second at an angle of 41 degrees what is the balls acceleration in the vertical direction as it flies through the air

The vertical component of the acceleration is equal to the acceleration due to gravity g.

Explanation:

Given data,

The initial velocity of the football, u = 31 m/s

The angle of direction of the football with the horizontal, Ф = 41°

In free fall, the vertical component of acceleration always remains the same.

Since the ball is clicked in a particular direction that has a vertical component,  then the vertical component of the velocity of the ball is always acted upon by the gravitational force of the earth.

The horizontal component of the velocity of the projectile remains the same because the gravitational force doesn't act in the horizontal direction.

Since the only force is the gravitational force acts on the projectile, the vertical component of the acceleration is equal to the acceleration due to gravity g.
