How would you work this physic's problem?

A baseball pitcher throws a fastball at a speed of 44 m/s. The acceleration occurs as the pitcher holds the ball in his hand and moves it through an almost straight line distance of 3.5 m. Calculate the acceleration, assuming it is uniform. Compare this acceleration to the acceleration due to gravity, 9.8 m/s^2.How would you work this physic's problem?
v^2 = s^2 + 2ax





v = final velocity


s = start velocity





44^2 = 0^2 + 2 x a x 3.5





1936 = 7a





a = 276.58 m/s^2
