Homework Statement
Let's suppose we have two objects on ##x## axis.They have mass ##m## and ##M##, They are exerting a gravitational force on each other and its magnitude can be written as ##F=\frac {mMG} {R^2}##.
So my question is can we find Instantaneous velocity of ##m##, ##{V_m}## ?
We only know ##R##, ##m## and ##M##.
Homework Equations
##W=ΔKE##
##F=\frac {mMG} {R^2}##.
The Attempt at a Solution
I tried to use ##W=ΔKE## but it didnt make sense cause we don't know inital conditions, like inital speed of the object etc. and cause of that I also couldn't use kinematic equations.
