Question 1129218: How much centripetal force is needed to keep a 0.38 kg ball on a 1.55 m string moving in a circular path with a speed of 3.0 m/s? Found 2 solutions by addingup, MathLover1:Answer by addingup(3677) (Show Source):
You can put this solution on YOUR website! The equation for Force is:
F = ma
where a = m/s^2
in this problem:
[0.38(3.0)^2]/1.55
(0.38*9)/1.55
you can finish it from here, the result will be the force needed as measured in Newtons
