You work in a factory that manufactures pistols (small guns). Your job is to test the quality of these pistols. One of the
important parameters is the speed of the bullets shot from these pistols. A successful pistol the factory makes is the
MS7.4. It is light and has mass 420 grams. According to the design engineers, the 20-grams bullet shot from this pistol
should have a speed about 650 m/s. You design a new speed measuring device. In this device, you have a small, white
box made of a very light weight material. You attach the box to a very stiff, horizontal spring whose constant is 4.0 x 10
N/m. You then bring an MS7.4 and fire it at the box and find the spring compresses by 46 cm. Does the pistol past the
quality test?
