starting with v - v0 = vexln(m0/m) where, v= final velocity v0 = initial velocity vex= exhaust speed relative to spacecraft m0= initial mass m = final mass because final velocity has to be zero and assuming constant exhaust speed, i simplified the above expression to get t. t...

Homework Statement A spacecraft of mass m0 is descending with velocity v0 to land on an alien plant where the value of g is 1/6 of g on the earth. In order to land safely (meaning the final velocity upon landing is zero), fuel has to be burnt at a constant rate dm/dt=-k, where k is a...
