Question #1: An experimental railgun fires a steel slug into a resisting medium for impact analysis. The steel slug hits the medium's surface at 900 [ft/s]. After impacting, the steel slug penetrates 4 [in] in the medium. The medium surface is defined as x = 0 . The velocity of the steel slug was experimentally determined to be (v = vo – kx) [ft/s]. Determine: a) The initial acceleration of the steel slug immediately after it hits the medium b) The time it takes for the steel slug to penetrate exactly 3.9 [in] Use the following diagram. X = 0 Vinitial Resisting Medium
