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.

An alligator swims to the left with a constant velocity of 5 \,\dfrac{\text{m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction. when the alligator sees a bird straight ahead, the alligator speeds up with a constant acceleration of 3 \,\dfrac{\text {m}}{\text s^2}3 s 2 m ? 3, space, start fraction, m, divided by, s, start superscript, 2, end superscript, end fraction leftward until it reaches a final velocity of 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction leftward. how many seconds does it take the alligator to speed up from 5 \,\dfrac{\text {m}}{\text s}5 s m ? 5, space, start fraction, m, divided by, s, end fraction to 35 \,\dfrac{\text {m}}{\text s}35 s m ? 35, space, start fraction, m, divided by, s, end fraction?
