At t 0, the object is moving with a positive initial velocity of vo and continues until its velocity reaches zero (if it ever does). -kv", k> 0, n 2 0 a constant. (This is (a) Show that the object comes to a rest in a finite amount of time if and only if n < 1 and find the maximum distance travelled in this case (b If 1 sn<2, show that the maximum distance travelled by the object in a finite time is less than (vo2-)/[(2 n)k]. (c) Show that if n 2 2, then there is no limit to the distance the object can travel.
