Question

A model rocket is shot straight up and explodes at the top of its trajectory into three pieces as viewed from above and shown in the figure below. The masses of the three pieces are

m_A = 110.0 g,

m_B = 20.0 g,

and

m_C = 30.0 g.

Immediately after the explosion, piece A is traveling at 1.40 m/s, and piece B is traveling at 6.90 m/s in a direction 30° below the negative x axis as shown. What is the velocity of piece C?

A missile is shot straight up into the air. At the peak of its trajectory, it breaks up into three pieces of equal mass, all of which move horizontally away from the point of the explosion. One piece travels in a horizontal direction of 35° east of north with a speed of 31 m/s. The second piece travels in a horizontal direction of 11° south of west with a speed of 7 m/s. What is the velocity of the remaining...

A model rocket has a mishap in air, and it explodes apart into two pieces. The 3.0 kg rocket was traveling at velocity <0, 9, 0> m/s just before the explosion, and the 2.0 kg piece of rocket is traveling at velocity <4, 8, 0> m/s just after the explosion. What is the velocity of the 1.0 kg piece just after the explosion?

A mortar fires a shell of mass m at speed v0. The shell explodes at the top of its trajectory (shown by a star in the figure) as designed. However, rather than creating a shower of colored flares, it breaks into just two pieces, a smaller piece of mass 15m and a larger piece of mass 45m. Both pieces land at exactly the same time. The smaller piece lands perilously close to the mortar (at a distance of zero from...

A vessel at rest at the origin of an xy coordinate system explodes into three pieces. Just after the explosion, one piece, of mass m, moves with velocity (-47 m/s) and a second piece, also of mass m, moves with velocity (-47 m/s) . The third piece has mass 3m. Just after the explosion, what are the (a) magnitude and (b) direction (as an angle relative to the +x axis) of the velocity of the third piece?

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,...
