Why do helium balloons floạt in air?
The air below the balloon moves upward, causing
the balloon to rise.
O The buoyant force exerted by the surrounding air
onto the balloon is greater than its weight.
The helium inside the balloon escapes, causing it
to float.
The pressure below the balloon is greater than
the pressure above the balloon, causing it to rise.

A commercial airplane is coming in for a landing. Just before it hits the runway it is moving at 76 m/s. The plane has a mass of 20,000 kg. The runway is 1.6km long and, obviously, the airplane needs to be stopped before it reaches the end of the runway. How large is the braking force the airplane needs to stop safely before the end of the runway?

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.
