Q. A bomb explodes into three pieces. A piece with the mass 4kg flies out with a velocity of 800 m/s downward. The second piece of mass 5kg flies out with a velocity of 700 m/s to the right. If the third piece has a mass of 6kg, find its velocity after the explosion.

Q. The man pulls the boy up to the tree limb C by walking backward at a constant speed of 1.1 m/s. Determine the speed at which the boy is being lifted at the instant x_A = 4 {rm m}. Neglect the size of the limb. When x_A = 0, y_B = 8 {rm m}, so that A and B are coincident, i. e., the rope is 16 {rm m} long.
