Ohhh, ok. Thank you Tide, much appreciated. I just missed that leap from setting up the integral to what you posted I guess. Thanks everyone.

Thank you both. I was pursuing Integral's method at first before running into the same problem. I agree with Tide's reasoning but I don't follow how you got to that integral, and even more so how I would solve that integral. Could you help with that? Thanks

I had this question in class the other day and need some help: A particle falls to Earth starting from rest at a great height. Neglecting air resistance, show that the particle requires about 9/11 of the total time of fall to traverse the first half of the distance. Anything would be...

Thanks both of you for your help, very much appreciated.

This question was posed in class the other day for extra credit: A rocket with initial mass 70000kg burns fuel at a rate of 250kg/s; it has an exhaust velocity of 2500m/s. If the rocket is at rest, how long after the engines fire will the rocket lift off? I've been trying to solve it...
