Question

An object of mass 0.5 kg is swung in uniform circular motion. The radius is 2 meters, and the force exerted is 4 N. Calculate the magnitude of the velocity.

Answer 1

\[F=\frac{ mv ^{2} }{ r }\rightarrow v=\sqrt{\frac{ Fr }{ m }}=\sqrt{\frac{ 4\times 2 }{ .5 }}=4(m/s)\]

Answer 2

Thanks a bunch!
