1. A block of mass m slides along a

horizontal surface lubricated with a thick oil which provides a drag force

proportional to the square root of velocity:

If v = v0 at t = 0, determine v

and x as functions of time.

2. Show that the maximum distance the block

in Problem 72 can travel is 2m V02/3 /3b.
