A pendulum consists of a 2.0-kg wooden block hanging on a 1.5-m length string. A 10-g bullet moving with a horizontal velocity strikes the wooden block (initially at rest) and embeds in the block, and the entire system swings through a height of h = 0.75 m. Answer the following questions a. Draw a diagram illustrating all the elements of the problem.
b. Find the initial speed of the bullet.
c. How much kinetic energy is released in this collision?
