1. A firework (small rocket) whose shell has a mass of m 12kg was initially on the ground before being launched to a height of 100m above the ground at which point its horizontal displacement from its starting position is 17.6m. At this location its speed is 68m/s and it's at an angle relative to (and above) the horizontal of 80 as depicted in the diagram below. Once it reaches this height it goes off and its shell splits into...

3. A gun tackle consits of a light rope and two ideal pulleys. One end of the rope is attached to the ceiling and wrapped around both pulleys, as depicted, while the other end is fastned to mass A. Mass B hangs off the pulley that is free to move. The second pulley is attached to the ceiling. Initially the blocks, which have the same mass, are suspended at the same distance from the ceiling and are subsequently released...

2. Artificial gravity is necessary for humans to stay healthy during extended stays in space. To provide artificial gravity, a space station is shaped like a cylinder with a diameter of 2200 m, and it rotates about its center at a constant rate. The astronauts live inside the cylinder at the outer edge, and feel a gravitational pull outwards. (a) How long should one revolution of the space station take if the acceleration of an astronaut on the outer edge...
