Hi
I need help with the following question. I have attached my question. I need help with part b)
this is what i have managed to do so far, but i don't think i am doing it correctly.
\(\displaystyle m\ddot{r}=\frac{mMG}{r^{2}}\)
dividing both sides my \(\displaystyle m\)
\(\displaystyle \ddot{r}=\frac{MG}{r^{2}}\)
\(\displaystyle \int\ddot{r}dt=\int\frac{MG}{r^{2}}dt\)
\(\displaystyle \dot{r}=\frac{MG}{r^{2}}t+C
\)
any help is appreichated
thanks
(Happy)
