Question

a ball that has a mass of 0.25 kg spins in a circle at the end of a 1.6 m rope. the ball moves at a tangential speed of 12.2 m/s. what is the centripetal force acting on the ball?
1.9 n
23 n
59 n
93 n

Explanation:

Step1: Recall the centripetal force formula

The formula for centripetal force is \(F = \frac{mv^{2}}{r}\), where \(m\) is the mass, \(v\) is the tangential speed, and \(r\) is the radius of the circular path.

Step2: Substitute the given values into the formula

Given \(m = 0.25\space kg\), \(v=12.2\space m/s\), and \(r = 1.6\space m\).
