Question #274962

A 50 kg object moves at 50 m/s around a circular path of radius 10m. What centripetal force is needed to keep it in its orbit? What is the centripetal acceleration of the object?

Expert's answer

The centripetal force needed to keep it in its orbit is

F_c=mv^2/r=12500\text{ N}.

The centripetal acceleration:

a_c=v^2/r=250\text{ m/s}^2.
