Two joggers are running with constant speed in opposite directions around a circular lake. One jogger runs at a speed of 2.15 m/s; The other runs at a speed of 2.55 m/s. The track around the lake is 300m long, and the two joggers pass each other at exactly 3:00 PM. How long is it before the next time the two joggers pass each other again?

[8 pts] Consider two people walking on a circular track of diameter 2 miles. They start on opposite sides of the diameter and walk at a constant rate of 4 miles per hour in the opposite directions (one clockwise, the other counterclockwise). Let a be the straight-line distance between the two people at any given time. Show that the rate of change of the distance between them is dc = -414-22 dt 0 a

(21 pts.) Two people are on a row boat out in the middle of a calm lake. Initially the boat and the people in the boat are at rest. The people, who are good swimmers, are standing in the boat and decide to race to shore. Since they are roughly in the middle of the lake, they decide to swim in opposite directions from one another. The people simultaneously dive from opposite ends of the boat. Person A, who weighs...

These questions concern a space station, consisting of a long
thin uniform rod of mass 4.3 x 10^6 kg and length 769 meters, with
two identical uniform hollow spheres, each of mass 1.7 x 10^6 kg
and radius 218 meters, attached at the ends of the rod, as shown
below. Please note that none of the diagrams shown is drawn to
