I know about Newtons law.. In free fall, with air resistance, the equation is something like: m*g - k*v = m*dV/dT. But this is for free fall, I guess the one I need is a little bit different?

A bullet fired vertically upwards with a beginning speed 70 m / s. In this task, we shall assume that the sphere is exposed to air resistance is proportional to the speed, and given by. Proportionality constant k = 1.6 * 10 ^ -2 kg / s and the bullets mass m = 0.100 kg. We expect that the...
