Unformatted text preview: off the front of the rocket (and also deploys a parachute to bring the body of the rocket down slowly). The nose cone has a mass of 0.05 kg. The mass of the rest of the rocket is 0.15 kg. The rocket body recoils from this charge with a velocity of 1 m/s. How far from the launch site will the nose cone land if the rocket were horizontal when the ejection charge fired? This is a multi-step problem: 1) Use momentum conservation to get the horizontal velocity of the nose cone. The nose cone will hit the ground with a vertical velocity of 45 m/s. 2) Use the definition of impulse to determine the time. 3) Distance equals velocity times time. 2 ) 2 / 1 ( mv KE mgh PE p dt F J v m p a m F...
