Rоcket Burn аnd Mаximum Altitude PHY 2048C Cumulаtive Final Examinatiоn Pоints: 10 Suggested Time: 25–30 minutes Instructions: Show all work. Begin each derivation with an appropriate fundamental physics principle. Clearly define any additional symbols you introduce. Unsupported answers may not receive full credit. A research rocket launches vertically from rest. During the powered portion of the flight, fuel is expelled downward at a constant speed u relative to the rocket. Fuel is consumed at a constant rate λ, so the rocket's mass ism(t) = m0 − λt, 0 ≤ t ≤ tbwhere m0 is the initial mass and tb is the burnout time. Assume m0 > λtb. Neglect air resistance, take upward as positive, and treat g as constant. After burnout, the rocket coasts upward under gravity alone. Tasks Part A. Starting from conservation of momentum for a variable-mass system, derive the rocket's velocity v(t) during the burn. Your final expression must be in terms of u, m0, λ, t, and g.Part B. Determine the rocket's burnout speed vb.Part C. Derive an expression for the vertical distance yb traveled during the powered portion of the flight. You may use the initial conditions y(0) = 0 and v(0) = 0.Part D. Determine the rocket's maximum altitude ymax above the launch point.Part E. State the minimum condition on u, λ, m0, and tb required for the rocket still to be moving upward at burnout.
