Christian Ottem pointed out that the first question in Problem 2(i) in Oblig1 is not quite precise. You may assume that alpha > 1 or alpha = 1 when answering this question. When 0 < alpha < 1 the solution is not unique (why?), but you can find a solution where the velocity converges to 0 when t tends to infinity (why?)
