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?Initial velocity= 0cm/sec

Final Velocity = (32cm/17.6sec)= (1.8cm/sec)

@&
You've divided displacement by change in clock time. This doesn't give you the final velocity. Be sure you connect this with the definition of rate of change.
*@

Average Velocity = .9 cm/sec

@&
If the final velocity was 1.8 cm/s then the average velocity, since the initial velocity was zero, would be .9 cm/s.

However 1.8 cm/s is not the final velocity.
*@

Acceleration = Vf(1.8)-Vi(0) / t(17.6)= .10m/s/s

@&
If 1.8 m/s was the final velocity this would be correct, and is correctly reasoned.
*@

@&
Despite the fact that you have one basic error in your first result, you're doing well here. Correct that result and the remaining results should correct themselves.
