An object travels a distance of 32 cm in 17.6 seconds from start to finish. If its acceleration is uniform and its initial velocity zero, then what are its average velocity, acceleration and final velocity?Average rate = change in position / time interval

Average rate = 32 cm / 17.6 seconds = 1.82 cm/sec

Acceleration = change in velocity / change in time

a = 3.64 cm/sec / 17.6 sec = 0.207 cm/sec^2

Final velocity = 2 * (average rate) = 3.64 cm/sec

&#Very good responses. Let me know if you have questions. &#
