if the mass of an objet was 325g calculate the centripital force acting on the object when the radius is 2.2metres. the object is being spun in a circle.

Question

anonymous · Answer

force = mass * v^2 / r
         = 0.325 v^2 / 2.2  Newtons

anonymous · Answer

I know the formulae, but what is the velocity?

anonymous · Answer

you have to know the velocity to calculate the force
you have two unknown variables here

anonymous · Answer

not my fault

anonymous · Answer

of course it's not your fault
the point is you haven't got enough information to find the value asked for

anonymous · Answer

as you can imagine, the faster the object spins in a circle the greater the force will be
