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 = 0.0065 kg, while that of the block is M = 0.98 kg. After the collision the block/bullet system swings and reaches a maximum height of h = 1.1 m above its initial height. Neglect air resistance. A: Enter an expression for the initial speed of the bullet in terms of defined quantities and g. B: Find the initial speed of the bullet, in meters per second. c: Find the initial kinetic energy of the bullet, in joules. d: Enter an expression for the kinetic energy of the block/bullet system immediately after the collision, in terms of defined quantities and g.
