 Homework Statement:

A small sphere of mass m is fastened to a weightless string of length 0.5m to form a pendulum. The pendulum is swinging so as to make a maximum angle of 60 degrees with the vertical.
a) What is the velocity of the sphere when it passes through the vertical position?
b) What is the instantaneous acceleration when the pendulum is at its maximum deflection?
 Relevant Equations:

a) v=sqrt(L*g*sine(thet)*tan(thet)
b) ac= v^2/r
