8. Two blocks of masses 8 kg and 4.3 kg are placed on a horizontal, frictionless surface.A light spring is attached to one of them, and the blocks are pushed together with thespring between them. A cord holding them together is burned, after which the block ofmass 4.3 kg moves to the right with a speed of 19 m/s. What is the velocity of the othermass in m/s?9. Am = 500 kg sack of coal falls vertically onto a M = 2000 kg railroad flatcarwhich was initially moving horizontally at 3 m/s. No external forces, includingfriction, acton the flatcar. After the sack rests on the flatcar, the speedof theflatcar is:a) 1.8 m/sb) 2.4 m/sc) 3.6 m/sd) 0.6 m/se) 1.2 m/s10. Each croquet ball in a set has a mass of 0.53 kg. The green ball, traveling at 11.9 m/s,strikes the blue ball, which is at rest. Assuming that the balls slide on a frictionlesssurface and all collisions are head-on, find the final speed of the blue ball if the greenball stops moving after it strikes the blue ball.11.

2. In a scifi movie about astronauts on a space station, one of the astronaut's safety line is cut while on a space walk. The astronaut, who 10 meters from the shuttle and is moving 0.1 m/s away from it, finds that the suit's thruster pack has also been damaged and no longer works and that only 30 seconds of air remains. To get back to the shuttle, the astronaut unstraps a 10-kg tool kit and throws it away with a speed of 5 m/s. In the scene, the astronaut, who has a mass of 100 kg without the toolkit, survives. Is this reasonable?
