To disable ballistic missiles during the early boost phase of their flight, an “electromagnetic rail gun,” to be carried in low-orbit Earth satellites, has been proposed. The gun might fire a 2.38-kg maneuverable projectile at 10.0 km/s. the gun might fire a 2.38-kg maneuverable projectile is sufficient on impact to disable a missile even if it carries no explosive. (A weapon of this kind is a “kinetic energy” weapon.) the projectile is accelerated to muzzle speed by electromagnetic forces. Suppose instead that we wish to fire the projectile using a spring (a “spring” weapon). What must the force constant be in order to achieve the desired speed after compressing the spring 1.47 m?
