course PHY 231
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? 32cm/17.6secs=1.818 cm/secs is the average velocity.
Since the acceleration is uniform that means it is constant so the acceleration is zero cm/s^2
The final velocity is 1.818 cm/s*2=3.636 cm/s
@& The average and final velocities are as you have given them.
It is clear that the velocity is changing, so the average rate of change of velocity with respect to clock time is not zero.
The acceleration is the ave rate of change of velocity with respect to clock time, so the acceleration is not zero.
See if you can reason out the acceleration from the information you have already obtained.
