    How to Calculate Time with Varying Acceleration Toward the Moon?

    Now i have v as a function of r: http://img443.imageshack.us/img443/527/16674494.jpg 6.67*10^-11 is the gravitational constant M is the moon mass R is the moon radius v(R) = 1679m/s so this is correct compared to the speed i found earlier. What to do next? I am completely blank... Do...

    How to Calculate Time with Varying Acceleration Toward the Moon?

    Okay, that helped me a bit further :) I now have this: http://img708.imageshack.us/img708/3463/formel.jpg For v i inserted what i used to get the speed when hitting the surface. But what should be inserted for ds here? I really appreciate you helping me here!

    How to Calculate Time with Varying Acceleration Toward the Moon?

    What equations do i have to integrate? I have tried to use all equation of motion and integrate them and i always end up with an extreme high number. Could you please try to explain this in more detail? I do not understand integrals very well..

    How to Calculate Time with Varying Acceleration Toward the Moon?

    Homework Statement A object is brought up to a distance of 2*R (R=moon radius) from the moon mass center and dropped. Starting velocity is 0. Calculate the velocity the object has when hitting the moon surface. Calculate the time it takes to reach the surface. Homework Equations...
