When a body is moving in circular path at a
distance r from its center its velocity at any
instant will be directed tangentially. This is
what we call tangential velocity. It is
calculated as follows:
Vt=r(w)
where w = 5 rev/s (2m rad / rev) = 31.42
rad/s
Vt = 0.24(31.42) = 7.5 m/s
What is the rest of the question
The answer is 2.25 hours, or 2 hours and 25 minutes.
9.50-5=4.50
4.50/2=2.25
Yes it’s true because of the size of the circle
