Newtons Laws Of Snow Plowing

Someone actually suggested that a snow plows speed does not play a role in how far snow is thrown ..... boggles the mind

Sir Issac Newtons Second Law of Motion says....The acceleration produced by a particular force acting on a body is directly proportional to the magnitude of the force and inversely proportional to the mass of the body. Or the equation:

Any Questions? I did not get it at first either.....

The faster the plow travels the further the snow is thrown.  The opposite is also true.  Think of a boat going slow, it produces a small wake.  The faster it goes the bigger the wake.  The size of the boat or ship also will determine the size of the wake.  Also think of a car driving down a flooded road.  If the car accelerates while going through a puddle, the water is displaced higher, farther, and with more force than if the car crept through the puddle. Do we all agree?

So the following comment in the TI Sun .... "that whether a wing truck travels at 30 mph or 10 mph it would have the same effect" [ of moving the snow the same distance with the same force] is simply physics from some other freaky universe.... not ours.

If you watch the video below, it is easy to visualize that speed has an effect at how far the snow is thrown and with what force..... Class dismissed
