a string 0.5 m long is used to whirl a 1 kg stone in a horiziontal circle at a uniform velocity of 5m/s what is the tension on the string?

• physical science -

the tension in the string provides the force for the centripetal acceleration of the stone

f = m * v^2 / r = 1 * 5^2 / .5

the force is in Newtons
