A ball is thrown off the edge of a roof with a starting velocity of 10 m/s and hits the ground at a final velocity of 40.4 m/s. The trip to the ground takes 3.2 seconds. What is the acceleration of the ball?

Question

Quizplus · Accepted Answer

Acceleration = change in velocity / change in time Vi = initial velocity (10 m/s) Vt = terminal velocity (40.4 m/s) Vc = chance in velocity (Vt - Vi) t = time (3.2 s) a = acceleration Fill in numbers: a = (40.4 m/s - 10 m/s) / 3.2 s a = 9.5 m/s²
