I am so terrible with what formulas to use or which information goes where in the formula. Can anyone help me??
If a 1.50 kg mass revolves at the end of a string 0.50 m long, and its tangential speed is 6.0 m/s, calculate the centripetal force.

I am so terrible with what formulas to use or which information goes where in the formula. Can anyone help me?? 
If a 1.50 kg mass revolves at the end of a string 0.50 m long, and its tangential speed is 6.0 m/s, calculate the centripetal force.

perl · Answer

Centripetal force for a mass that moves in uniform circular motion is 
F = mv^2/r 

We can substitute the given velocity and mass
force = 1.5 kg * (6m/s)^2 / (0.5 m)

perl · Answer

in the formula v is the tangential velocity
