Question

A football is kicked with a velocity of 18 m/s at an angle of 20. What is the balls acceleration in the horizontal direction as it flies through the air

Answer 1

My apex test just corrected my original answer of 9.8 m/s^2 to 0 m/s^2.

Answer 2

If we perform all of our experiments on Earth and ignore
air resistance, then vertical acceleration is always 9.8 m/s²
downward, and horizontal acceleration is always zero.
