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...
