A 30g bullet with a speed of 400m=s strikes a glancing blow to a
target brick of mass 1:0kg. The Brick breaks into two fragments.
The bullet deflects at a angle of 30� above the +x-axis and has a
reduced speed of 100m=s. One piece of the brick with mass
(0.75kg) goes off to the right with a speed of 5:0m=s. Determine
the speed and direction of the other piece of the brick immediately
after the collison.
