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 = 1.05 m above its initial height. neglect air resistance.

Enter an expression for the kinetic energy of the block/bullet system immediately after the collision, in terms of defined quantities and g.
