The brake mechanism used to reduce recoil in certaintypes of gun consists essentially of a piston attachedto the barrel and moving in fixed cylinder filled with oil.As the barrel recoils with initial velocity v0, the pistonmoves and oil is forced through orifices in the piston,causing the piston and the barrel to decelerate at arate proportional to their velocity; that is, a = -kv.Express a) v in terms of t, b) x in terms of t, c) v interms of x. Draw the corresponding motion curves.
