Question

An object with mass m = 0.56 kg is attached to a string of length r = 0.72 m and is rotating with an angular velocity ω = 1.155 rad/s. What is the centripetal force acting in the object?

Answer 1

The centripetal force is 0.54 N.

Step-by-step explanation:

mass, m = 0.56 kg

radius, r = 0.72 m

angular speed, w = 1.155 rad/s

The centripetal force is given by

`F = m r w^2\\\\F =0.56* 0.72* 1.155* 1.155\\\\F = 0.54 N`
