A rocket is fired straight up, burning fuel at the constant rate of \(b\) kilograms per second. Let \(v=v(t)\) be the velocity of the rocket at time \(t\) and suppose that the velocity \(u\) of the exhaust gas is constant. Let \(M=M(t)\) be the mass of the rocket at time \(t\) and note that \(M\) decreases as the fuel burns. If we neglect air resistance, it follows from Newton's Second Law that \(F=M \frac{d v}{d t}-u b\) where the force \(F=-M g\). Thus Let \(M_{1}\) be the mass of the rocket without fuel, \(M_{2}\) the initial mass of the fuel, and \(M_{0}=M_{1}+M_{2}\). Then, until the fuel runs out at time \(t=M_{2} / b\), the mass is \(M=M_{0}-b t\). (a) Substitute \(M=M_{0}-b t\) into Equation 1 and solve the resulting equation for \(v\). Use the initial condition \(v(0)=0\) to evaluate the constant. (b) Determine the velocity of the rocket at time \(t=M_{2} / b\). This is called the burnout velocity. (c) Determine the height of the rocket \(y=y(t)\) at the burnout time. (d) Find the height of the rocket at any time \(t\).

A rocket is fired straight up, burning fuel at the constant rate of b kilograms per second. Let v = v(t) be the velocity of the rocket at time t and suppose that the velocity u of the exhaust gas is constant. Let M = M(t) be the mass of the rocket at time t and note that M decreases as the fuel burns. If we neglect air resistance, it follows from Newton’s Second Law that where the force F = ?Mt. Thus Let M1 be the mass of the rocket without fuel, M2 the initial mass of the fuel, and M0 = M1 + M2. Then, until the fuel runs out at time t = M2/b, the mass is M = M0 ? bt. (a) Substitute M = M0 ? bt into Equation 1 and solve the resulting equation for v. Use the initial condition v(0) = 0 to evaluate the constant. (b) Determine the velocity of the rocket at time t = M2/b. This is called the burnout velocity. (c) Determine the height of the rocket y = y(t) at the burnout time. (d) Find the height of the rocket at any time t.
