Aspring gun is made by compressing a spring in a tube and then latching the spring at the compressed position. a 4.97-g pellet is placed against the compressed and latched spring. the spring latches at a compression of 4.60 cm, and it takes a force of 9.12 n to compress the spring to that point. (note: while the spring is being compressed the ball is not in contact with the spring.) (a) if the gun is fired vertically, how fast is the pellet moving when it loses contact with the spring? (include the effect of gravity and assume that the pellet leaves the spring when the spring is back to its relaxed length.)

Asubmarine has a "crush depth" (that is, the depth at which water pressure will crush the submarine) of 250 m. what is the approximate pressure (water plus atmospheric) at this depth? (recall that the density of seawater is 1025 kg/m3, g = 9.81 m/s2, and 1 kg/(ms2) = 1 pa = 9.8692 10-6 atm.) a. 34.8 atm b. 24.8 atm c. 25.8 atm d. 7.8 atm

Asatellite component is in the shape of a cube with 10cm edges, has an evenly distributed mass of 2 kg and one bolt hole at each of four corners. if the maximum predicted random vibration environment is 10 grms, what bolt size would be a good choice for restraint? what other factors might drive bolt size besides force/stress?
