Apply conservation of energy. When the block is at one extreme, the kinetic energy is equivalent to 0, while potential energy is available. Assuming no loss of energy (through noise and heat), the potential energy should be equal to the kinetic energy of the bullet before collision. Apply conservation of energy.
