Solve the problem.The velocity of a body of mass m falling from rest under the action of gravity is given by the equation 
where k is a constant that depends on the body's aerodynamic properties and the density of the air, g is the gravitational constant, and t is the number of seconds into the fall. Find the limiting velocity, 
v, of a 380 lb. skydiver (mg = 380) when k = 0.006.
A. 251.66 ft/sec
B. 0.01 ft/sec
C. There is no limiting speed.

Solve the problem.The figure below shows the paths that run through a nature park. Have the paths been designed in such a way that it is possible for a visitor to find a route that begins and ends at the entrance (represented by vertex A) and that goes along each path exactly once? If so, use Fleury's algorithm to find such a route.
