Model the fuel burning as a steady ejection of small pellets, each with the small mass δm. suppose it takes a short time δt to accelerate a pellet (at constant acceleration) to the exhaust speed vex. further, suppose the rocket is clamped down so that it can't recoil. find an expression for the magnitude of the force that one pellet exerts on the rocket during the short time while the pellet is being expelled.
