## Homework Statement

For a conical pendulum:

Construct a free-body diagram for the pendulum and derive an expression for the acceleration in terms of the gravitational field strength g, the length L of the pendulum, the radius r of the circular path of the pendulum, and the frequency f of oscillation. (Hint - first derive an expression for tanθ the angle between the string and the vertical.)

## Homework Equations

a=v^2/r

a=Δv/Δt

a=ƩF/m

## The Attempt at a Solution

Have done free body diagram, can't figure out how to make equation.
