Question

Two people start at the same place and walk around a circular lake in opposite directions. One has an angular speed of 1.2 10-3 rad/s, while the other has an angular speed of 3.4 10-3 rad/s. How long will it be before they meet?

Answer 1

time=2PIrad/(1.2E-2 +3.4E-3)rad/sec

Both together transverse 2PI radians.
