A 2 kg rock is released from rest at the surface of a calm lake. If the resistance offered by the water as the rock falls is directly proportional to the rock’s velocity, the rock’s acceleration is a=g−Cdvm , where g is the acceleration of gravity, Cd is a constant drag coefficient, v is the rock’s velocity, and m is the rock’s mass. Letting Cd = 4.1 kg/s, determine the rock’s velocity after 1.8 s.
