Okay, so I just recently purchased a book from Barnes and Nobles on Physics. I've taken a university level Physics course, so I have a general knowledge of some concepts. I was reading something that I'm not sure holds water. Here's the problem: Two men are standing on a sheet of ice. The larger of the two men is a giant weighing 300 kg while the smaller man reaches out and pushes the the larger man with all of his might--a total force of 10 Newtons. What will be the result of this action? Which of the two will slide across the ice and with what velocity? The book goes on to calculate the accelerations of both parties using F = ma. The acceleration for the bigger man is 0.333 m/s^2 and 0.1 m/s^2 for the smaller man. But they lose me because they use the words acceleration and velocity interchangeably. They say that the "larger man will slide backward with a velocity of 0.333 m/s while the smaller man will slide at 0.1 m/s." If this is the case, wouldn't the larger man slide faster? The conclusion that the book wants to get at is that the smaller man will move much easier on the ice, but how do you justify this using acceleration?
