In 5 seconds, the speed of the ball increased from 2 m / s to 5 m / s. Determine the acceleration of the ball.

Task data: t (the duration of the increase in the speed of the ball) = 5 s; V1 (initial velocity of the ball) = 2 m / s; V2 (final velocity of the considered ball) = 5 m / s.
To determine the acceleration of the ball in question, you must use the formula: a = (V2 – V1) / t.
Let’s calculate: a = (5 – 2) / 5 = 0.6 m / s2.
Answer: The speed of the ball in question increased with an acceleration of 0.6 m / s2.
