To calculate the acceleration of the ball, we can use the formula:
acceleration (a) = (final velocity (v) - initial velocity (u)) / time (t)
Given: Initial velocity (u) = 15 m/s Final velocity (v) = 60 m/s Time (t) = 5 s
Using the formula, we can substitute the given values:
a = (60 m/s - 15 m/s) / 5 s
Simplifying the equation:
a = 45 m/s / 5 s
a = 9 m/s²
Therefore, the acceleration of the ball is 9 m/s².
