An object is dropped from a tall building, If the air resistance is proportional to the square of the velocity, then (dv/dt)=-32(ft/sec^2)+kv^2 where k is a constant. Show that the velocity v as a function of time is v(t)= [squareroot(32/k)][tanh(squareroot(32kt))]

Solution Summary

This shows how to work with velocity and time.
