an object mass of .5kb revovles uniformly in cirlce horizontal frictionless surface. it is attached by .75 m cord to pin set in surface. if object makes 2 complete revolujtions per second, find its speed and its centripetal force(adsbygoogle = window.adsbygoogle || []).push({});

mg = m(v2/r)

gr = v2

v = sq root of gr

v = sq root of 9.8*.75

v = 2.7 m/s2

anyone wanna do me a favor, and check if i'm doing' this right,

thanks a lot..
