A simple pendulum has a length of 2.5 m and is pulled a distance y = 0.25 m to one side and then released (Fig. P11.24). (a) What is the speed of the pendulum when it passes through the lowest point on its trajectory? (b) What is its acceleration in the direction along its circular arc when it passes through the lowest point on its trajectory?
