A body of mass 7 kg is projected vertically upward with an initial velocity 18 meters per second. The gravitational constant is g=98m/s2. The air resistance is equal to k|v| where k is a constant.
Find a formula for the velocity at any time ( in terms of k ):
Find the limit of this velocity for a fixed time t0 as the air resistance coefficient k goes to 0.
