A wooden brick with mass M = 2 kg is suspended at the end of cords as shown above. A bullet with mass m = 3 g is fired toward the brick with speed v0 = 1 x 103 m/s. The bullet collides with the brick embedding itself into the brick. The brick-bullet system will swing upward after the collision.
(a) During the collision of the brick and the bullet, compare the magnitude and direction of the impulse acting on the brick to the impulse acting on the bullet. Justify your answer.
(b) Calculate the magnitude of the velocity v of the brick-bullet system just after the collision.
(c) Determine the ratio of the final kinetic energy of the brick-bullet system immediately after the collision to the initial kinetic energy of the brick-bullet system.
(d) Determine the maximum vertical position above the initial position reached by the brick-bullet system.
