Given:
- A semi-circle of radius = 3.2 m
- Time taken by object = 4 seconds
To find:
- Average speed of object = ?
- Average velocity = ?
Solution:
We know, velocity = Displacement/time.
Here, in circular motion the displacement is 2×pi×r.
Hence, the average velocity in circular motion = 2×pi×r/time
Since, it's a semi-circle so the velocity in circular motion will also be halved.
So, the final formula will be applied is:
(putting values for average velocity)...
==> 17.6 m/s
Hence, the average velocity of the object = 17.6 m/s
