A rock falls from rest off a high cliff. How far has the rock fallen when its speed is 39. 2 meters per second? [neglect friction. ].

The rock has fallen 78.4 meters

If you assume that rock starts at a speed of zero V0=0 kinetics formulas can be used to determine the change in distance from the start of acceleration to right before it hits the ground at 39.2 m/s

It is good, unless you eat a lot of it. it contains sugar.

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.
