During a test of a bulletproof vest, a handgun is fired at point blank range. the mass of the bullet is 2.12 g and it takes .341 s to travel through the gun barrell, during this time it has a constant acceleration of 334m/s^2. upon hitting it, the bullet causes the vest to move inward, eventually stopping without puncturing it. if the elastic fibers in the vest have a force constant of 2.37 x 10^5 n/m, how far does the vest move inward when it stops the bullet? the bullet travels horizontally after leaving the gun barrel; air reststance can be ignored; the motion of the elastic fibers in the vest can be considered simple harmonic.
