6 points) A Wooden block of mass M-1 ke is hanging from a string 50 cm long. A 3 gram bullet is tired at block of wood as shown below (left drawing). The bullet embeds itself in the wood, and the block swings up on the right to a maximum height such that the pendulum string makes an angle of 30° with respect to the vertical. How fast was the bullet going before it hit the wooden block? L-50 cm...

A simple pendulum consists of a ball of mass M hanging from a uniform string of mass m and length L, with m << M. (a) If the period of oscillations for the pendulum is T, derive an expression for the speed of a transverse wave in the string when the pendulum hangs at rest in terms of m, M, T and g (the acceleration due to gravity). Your expression should not include L. (b) If the string is made...
