12) A 2.0 kg firecracker that was initially sliding along the floor at 1.0 m/s (to the right) explodes with an internal energy of 10,000 J. If the firecracker breaks into two pieces that move in opposite directions, with the first piece having a mass of 0.75 kg and a speed of 30 m/s (to the right), then how much energy was converted into heat during the explosion? A) 0 kJ B) 1.5 kJ C) 2.7 kJ D) 4.3 kJ...

A giant "egg" explodes as part of a fireworks display. The egg is at rest before the explosion, and after the explosion, it breaks into two pieces, with piece B moving in the positive x direction. The masses of both pieces are indicated in (Figure 1) , shown traveling in opposite directions. The component of the momentum of piece B, pBx,f, is measured to be +500 kg?m/s after the explosion. Find the component of the momentum pAx,f of piece A...

A bomb at rest at the origin of an xy-coordinate system explodes into three pieces. Just after the explosion, one piece, of mass 2 kg, moves with a velocity of 43 m/s in the negative x-direction, and a second piece, also of mass 2 kg, moves with a velocity of 30 m/s in the negative y-direction. The third piece has a mass of 7 kg. What is the initial momentum of the bomb before the explosion? What is the x-component...

1- A block slides along a frictionless surface at 2.4 m/s. A second 3.5-kg block, sliding at a faster 7.5 m/s, collides with the first from behind and sticks to it. The final velocity of the combined blocks is 4.6 m/s. What was the mass of the first block? 2-A 15 g ball of clay traveling west at 4 m/s collides with a 50 g ball of clay traveling 30° north of east at 3.5 m/s. What is the speed...
