2. A bullet enters a resistive medium at x = 0 with an initial velocity vo = 900 ft/s and travels 4 inches before coming to velocity 0. Assuming that the velocity of the bullet is defined by the relation v = vo - kx, where v is expressed in ft/sec andx in ft determine a) the initial acceleration of the bullet, b) the time required for the bullet to penetrate a distance of 2 inches into the resistive medium.
c) The graph of velocity vs. position (v-x) and position vs. time (x-t).
This exercise is about statics
