Answer

Explanation:

Step1: Analyze vertical motion

The football moves up and down due to gravity. Gravity causes a constant vertical acceleration ($g = 9.8\ m/s^{2}$ down - ward), not a changing vertical acceleration. So the first statement is false.

Step2: Consider motion analysis method

Projectile motion is best analyzed by considering the vertical and horizontal components separately. The vertical motion is a uniformly - accelerated motion (due to gravity) and the horizontal motion is a uniform motion (assuming no air - resistance). So the second statement is true.

Step3: Analyze horizontal motion

In the absence of air - resistance, the horizontal component of the velocity of a projectile is constant. So, it advances sideways in equal amounts in equal time intervals. The third statement is true.

Answer:

It would be easiest to calculate it by considering the vertical and horizontal components separately; It advances sideways in equal amounts because it has a constant horizontal velocity.
