An athlete whirls a 7 kg hammer tied to the end of a 1.3 m long chain in a horizontal circle. The hammer makes one revolution in 1 s. What is the centripetal force (and direction!)acting on the hammer

The centripetal force acting on the hammer is 358.9 N and it is directed inwards.

The given parameters:

The angular speed of the hammer is calculated as follows;

The centripetal force acting on the hammer is calculated as follows:

The centripetal force acting on the hammer is 57.14 N.

Explanation:

Given that,

Mass of the hammer, m = 7 kg

Length of the chain, l = 1.3 m

The hammer makes one revolution in 1 s. The length of the chain will be the radius of the circular path. So, the formula of centripetal force is given by :

Here,

So, the centripetal force acting on the hammer is 57.14 N. Hence, this is the required solution.
