a rocket shot at 22m/s at 75 degrees above the horizontal explodes into four equal pieces at the highest point of its trajectory. One piece moves horizontally at 2m/s, a second one moves vertically upward at 3m/s and a third moves at 1.5 m/s vertically downward. What is the velocity of the fourth piece?

A rocket used for fireworks explodes just when it reaches its highest point in a vertical trajectory. It initially bursts into three fragments with masses of m, 3m, and 4m, each of these to explode slightly later. If the 4m fragment falls vertically with an initial velocity of 8 m/s, and the 3m fragment is ejected with a velocity of 10 m/s at an angle of 30° above the horizontal, find the velocity of the third fragment.

A cannonball of mass 27.6 kg is shot into the air at an angle of 45 degrees with respect to horizontal. At the top of its ballistic trajectory, the cannonball suddenly explodes into two separate pieces, a smaller piece this is 1/3 the original mass, and a larger piece that is 2/3 the original mass. The smaller piece ends up landing right back at the spot where the cannonball was originally launched, 14.7 seconds after it was launched. How far...

At an Independence Day celebration show, a large firework is
shot from the ground and, in the first stage of its bursting
pattern, splits into two unequal parts.
Assume that the firework has a mass of m_o = 0.30 kg and is
launched from a cannon at an angle of theta_o= 48.8° with an
initial velocity of v= 20 m/s. Just as the firework reaches its
hight point in its trajectory, it explodes into two pieces.
Immediately after the explosion,...
