A bullet is fired horizontally into an initially stationary block of wood suspended by a string and remains embedded in the block. The bullet’s mass is m = 0.0095 kg, while that of the block is M = 0.94 kg. After the collision the block/bullet system swings and reaches a maximum height of h = 0.95 m above its initial height. Neglect air resistance. Part A: Enter an expression for the initial speed of the bullet in terms of defined quantities and g. Part B : Find the initial kinetic energy of the bullet, in joules.
