To find the acceleration of an object, we can use the following equation:
acceleration (a) = (final velocity (v) - initial velocity (u)) / time (t)
Given: Initial velocity (u) = 0 m/s (starting from rest) Final velocity (v) = 60 m/s Time (t) = 3 seconds
Using the equation above, we can calculate the acceleration:
a = (v - u) / t = (60 m/s - 0 m/s) / 3 s = 60 m/s / 3 s = 20 m/s²
Therefore, the acceleration of the object is 20 m/s².
