Question

An 85 kg object is moving at a constant speed of 15 m/s in a circular path, which has a radius of 20 meters. What centripetal force is exerted on the body?

Answer 1

In circular motion,

Centripetal Force = Centrifugal force

Therefore, Force, F = $\frac{m[tex]v^{2}$}{r}[/tex]

                                 = $\frac{85×(15)²}{20}$

                                 = 956.25 N

And that's your answer...

Answer 2

Hi dear !!!

here is your answer !!!

centripetal force = mv² / R

=> 85kg × 15×15 / 20

956.25 N

hope it help you dear !!!

thanks !!
