Question

A rocket coasts in an elliptical orbit around Earth. To attain the greatest amount of KE for escape for a given amount of fuel, should it fire its engines to accelerate forward when it is at the apogee or at the perigee? (Hint: Let the formula $F d=\Delta \mathrm{KE}$ be your guide to thinking. Suppose the thrust $F$ is brief and of the same duration in either case. Then consider the distance $d$ the rocket would travel during this brief burst at the apogee and at the perigee.)

Step 1

1 of 2Kinetic energy is a product of mass of an object and its velocity squared. This means that in equation '$Fd=\Delta E_k$' distance satellite will travel during a short burst is proportional to the difference in velocity $\textbf{squared}$.
