A gondola on an amusement park ride spins at a speed of 15 revolutions per minute. If the gondola is 24 feet from the ride's center, what is the linear speed of the gondola in miles per hour?
Christian is making a Tyrolean traverse as shown in the
figure. That is, he traverses a chasm by stringing a rope
between a tree on one side of the chasm and a tree on
the opposite side, 25 m away. The rope must sag
sufficiently so it won't break. Assume the rope can provide
a tension force of up to 26 kN before breaking, and use a
"safety factor" of 10 (that is, the rope should only be
required to undergo a tension force of 2.6 kN) at the
center of the Tyrolean traverse.

safety range and Christian's mass is 72.0 kg
