A sledge of mass m = 85 kg has initial velocity v0 = 45 m/s and is moving horizontally along a straight line. The net force acting on the sledge is solely due to air resistance and is given by F = −k v2, where the constant is given by k = 1.2 kg/m. Find where the sledge will come to a stand still.

2. Relevant equations

I worked out that the velocity is given as v=(mv0)/(m+tkv0).

3. The attempt at a solution

I tried setting the velocity=0 but obviously that gives no answers. I then tried to differentiate the velocity to get the acceleration but I don't think this is the right route to go down.
