A simple pendulum has a length of 4.9 m and is pulled a distance y = 0.5 m to one side and then released.
(a) What is the speed of the pendulum when it passes through the lowest point on its trajectory?
(b) What is its acceleration when it passes through the lowest point on its trajectory?
I think this is the equation I am supposed to use? omega=sqrt(2(9.8)(L(1-cos(a))) where omega is velocity max and L is length of pendulum, a is angle between Pendulum and its starting position
Not totally sure what to do with equations...
The Attempt at a Solution
I tried solving for a and I got 1.262896 radians
then a final speed of 9.287 m/s
