A boat of mass m is pushed away from the berth with the initial speed v0. Suppose that the drag force f is proportional to the velocity of the boat; the second Newton’s law implies ma = −kv where v is the velocity of the boat, a is acceleration, k > 0 is the drag coeffinient. (a) Find the velocity of the boat as a function of time t. Your solution may involve v0, m, k as parameters. (b) Find...

A beach ball is thrown upward with initial speed v0. Assume that the drag force from the air is F = −mαv. What is the speed of the ball, vf , when it hits the ground? (An implicit equation is sufficient.) Does the ball spend more time or less time in the air than it would if it were thrown in vacuum? Where is the time needed in space vacuum is t = 2v0 / g .
