(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

I need to solve:

[itex] a=-\frac{1}{y[t]^2}+Exp[-y[t]]y'[t]

[itex]

Using Mathematica. I have tried NDsolve and nothing.

By the way a is acceleration,y is position,and y' is velocity.

y[0]=1000000, y'[0]=0,y''[0]=0

2. Relevant equations

3. The attempt at a solution

I have tried NDsolve and nothing.

Totally at a loss. This is this right equation this problem of mine by the way[checked with the prof]. I just need to graph a[t],y[t], and v[t].
