A hiker, who weighs 919 N, is strolling through the woods and crosses a small horizontal bridge. The bridge is uniform, weighs 4410 N, and rests on two concrete supports, one on each end. He stops 1/3 of the way along the bridge. What is the magnitude of the force that a concrete support exerts on the bridge (a) at the near end and (b) at the far end?
A gymnast with mass m1 = 49 kg is on the balance beam that sits on (but is not attached to) two supports. The beam has a mass m2 = 126 kg and length L = 5 m. Each support is 1/3 of the way from each end. Initially the gymnast stands at the left en..

An 88 kg spacewalking astronaut pushes off a 640kg satellite, exerting a 640N force for the 0.60 s it takes him to straighten his arms.
A tank having a volume of 0.100 m3 contains helium gas at 135 atm. How various balloons can the tank blow up if each filled balloon is a sphere 0.300 m in diameter at an absolute pressure of 1.50 atm.
You found the distance that you will cover at the same time as braking. You can utilize the expected amount of time for braking to check your answer for distance.
Assume that the rod is held at rest horizontally and then released. (Throughout the remainder of this problem, your answer may include the symbol, moment of inertia of the assembly, whether or not you have answered the first part correctly.)
