Calculate Acceleration of object in Circular motion

[Jordash]

Homework Statement

A conical pendulum is made of a ball on the end of a string, moving in circular motion as represented in the figure below. The length L of the string is 1.70 m, the angle θ is 37.0o, and the ball completes one revolution every 2.30 s

Calculate the acceleration of the ball, by first deriving a symbolic equation

The Attempt at a Solution

 

[Astronuc]

Please show some effort and work.

The ball is moving in a circular motion. Find the radius from the length of the string from pivot to ball, and the angle.

Acceleration is simply the change in velocity with respect to time.
