A ball of mass m is released from rest at x=0. Air resistance is expressed as R = kv2 , where k is a positive constant and v denotes velocity.
Derive an expression for the speed in terms of the distance x that it has fallen.
Identify the terminal v.
I know I have to start with ma = mg - kv2 and integrate but I can't seem to separate the variables right to get it as function of x or distance (even though the problem has a picture of a vertical fall)
