A 0.580-kg rock is tied to the end of a string and is swung in a circle with a radius of 0.500 meters. The velocity of the rock is 4.50 m/s. What is the centripetal force acting on the rock?

how do i find centripetal force??

  • NOT chemistry -

    Centripetal force = M V^2/R

    M is the mass, etc.

    The subject is called physics.
