1. For small, heavy bodies with large terminal velocities, a
better approximation for the force of air resistance is F =
bv2. Show that for x0 = v0= 0
at t0= 0, the velocity and position are given by the
following relations:
Where (mg/b)1/2 is the terminal velocity.
2. A boat moves with an initial speed v0 that is
slowed down by a frictional force.
F= -beav
a) Find its motion.
b) Find the time and distance for it to stop.
