A student has measured the force output from using a lever at various effort distances and input forces. The distance over which the load travels was held constant.  The student varied the input force and the distance by which the force was applied and plotted the points using a bar graph.
The student did not label the data plotted in the bar graph. Using your knowledge of mechanical advantage, which data correspond with the input force and which data correspond with the output force?
A.
The darker bars are the input force, the lighter bars are the output force.
B.
The lighter bars are the input force, the darker bars are the output force.

Abird flies directly overhead from where you stand at an altitude of 300.0 m and at a speed horizontal to the ground of 20.0 m/s. the bird has a mass of 2.0 kg. the radius vector to the bird makes an angle \thetaθ with respect to the ground. the radius vector to the bird and its momentum vector lie in the xyxy-plane. what is the bird’s angular momentum about the point where you are standing?
