Answer:
The vertical component of the acceleration is equal to the acceleration due to gravity g.
Step-by-step 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.
