Question: Problem 11.16 A projectile enters a resisting medium at x = 0 with an initial velocity v = 1000 ft/s and travels 3 in. before

Problem 11.16 A projectile enters a resisting medium at x = 0 with an initial velocity v = 1000 ft/s and travels 3 in. before coming to rest. Knowing that the velocity of the projectile is defined by the relation v = v - kx, where v is expressed in ft/s and x is in feet, determine (a) the initial acceleration of the projectile, (b) the time required for the projectile to penetrate 2.5 in. into the resisting medium.
