In summary, the radial acceleration of a pendulum with string length "L" and mass "m" at an angle of θ can be found by using the equation for centripetal acceleration, which depends on the velocity "v" and the radius "L". However, since the velocity is not constant and is instead a function of θ, this function must be determined in order to calculate the magnitude of the radial acceleration. This calculation also involves the acceleration due to gravity "g".

A pendulum (with string length "L") and aball of mass "m" is pulled back to a horizontal position and then released. Assuming that θ is the angle between the string and the vertical, find (a.) the magnitude of the radial acceleration of this ball at an angle of θ as a function of m,g, L, and/or θ.


I think I found what "V" is but I am not completely sure.

You know from the equation for centripetal acceleration that a is going to depend on v and the radius, which is L in this case. However, v is not constant, but rather is a function of theta. You need to find this function.
