Abullet is firef horizontally into an initially stationary block ofwood suspended by a string and remains embedded in the block. Thebullets mass is m=0.0085kg while that of the block is M=0.99kg.After the collision the block/bullet system swings and reaches amaximum height of h=1.15m above inital height. Neglect airresostance. A.)Enter an expression for the speed of theblock/bullet system immediately after the collision in terms ofdefined quantities and g. b.)enter an expression for the initalspeed of the bullet in terms of defined quantities and g. c.) enteran expression for the kinetic energy of the block/bullet systemimmediately after the collision in terms of defined quantities andg.
