Q. Pretend a person can walk only at a certain pace no faster, no slower. If you time her uninterrupted walk across a room of known length, you can compute her walking speed. If, however, she stops momentarily along the technique to greet others in the room, the extra time spent in her brief interactions gives an average speed across the room that is less than her walking speed. How is this like light passing throughout glass? In what way is it not? Explain.
Two automobiles, each of mass 900 kg, are moving at the same speed, 15 m/s, when they have an inelastic collision.(a) In what direction and at what velocity does the wreckage move if one car was driving north and one south? (b) In what direction a..

A canoe has the velocity of 0.420m/s southeast relative to the earth. The canoe is on a river that is flowing at 0.570m/s east relative to the earth.
What is an acceleration of the car
Giancoli, page 30 --when they say that x-xo increases with the square of the initial speed. Why do they say square of initial speed only, what about square of final speed? And why do they ignore that the distance also decreases by a factor of 2.
A box weighing 77.0 N rests on a table. A rope tied to the box runs vertically upward over a pulley and a weight is hung from the other end. Determine the force that the table exert on the box if the weight hanging on the other side of the pulley ..
