What is the centripetal force on the moving object?An object weighing 14n is swung at the end of a cord .80m long. The object makes 2.0 revolutions per second. ?
Fc = centripetal force = mv^2/r = m r w^2
w = angular speed = angled turned /time taken = 4pi/1 [rad/sec]
w = 4 * (22/7) = 88/7
weight = mg = 14 Newton
m = 14/9.8 kg
Fc = [14/9.8] [0.80] [88/7]^2
= 180.62 N
