A mass m is connected to a massless rope of length L, held at the horizontal position, and released to swing freely downward, as shown. (a) How fast is the mass moving at the bottom of its path? (b) What is the tension in the string at the bottom of its path? Now a peg is placed 4/5 of the way down the pendulum's path so that when the mass falls to its vertical position it hits and wraps around the peg. As it wraps around the peg and attains its maximum height it ends a distance of 3/5 L below its starting point (or 2/5 L from its lowest point). (c) How fast is it moving when it passes over the peg? (d) What is the tension in the string at this point
