Bit of help with this one if poss.. A vehicle has acceleration f(t) = a/(1+t)^n where a > 0, n>1(n not equal 2) are const. Find x dot of (t) and x(t) x(0)=x dot x(0)=0 what is the max speed poss??

so we have ... This is a seperable ODE solving gives Using the intial condition v(0)=0 we get so solving for C we get So so now we get This is also a seperable ODE. So just repeate the process from above. You should be able to finish from here
I don't understand how you know you get on the top when you're solving for C... in fact, so the power of the (1+0) is bound to be positive surely? Surely it should just be ? Also, I don't get where has come from either
