To find the acceleration of the ball, we can use the formula for acceleration, which is given by:
where
is the acceleration,
is the change in velocity, and
is the change in time.Given that the initial velocity of the ball is 3 m/s and the final velocity is 37 m/s, we can calculate the change in velocity as:
The change in time is given as 2 seconds.Substituting these values into the formula, we get:
Therefore, the acceleration of the ball is 17 m/s².
