A cannonball of mass 22.4 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 that is 1/3 the original mass, and a larger piece that is 2/3 the original mass. The two pieces fly apart horizontally, and the smaller piece ends up landing right back at the spot where the cannonball was originally launched, 11.2...
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,...
