1. The problem statement, all variables and given/known data Two marbles roll off a table at the same moment. One of the marbles has a horizontal speed of 1 inch per second, and the other has a horizontal speed of 4 inches per second. a) Which marble hits the ground first? b) If the table surface is 3 feet from the ground, what are the speeds of the marbles as they hit? 2. Relevant equations Don't know, as I can not use normal physics equations to solve for this problem (as my calc professor never mentioned/ used the physics equations to solve such problems in this chapter). Some how derivatives and integrals come into play.. 3. The attempt at a solution a) The marble traveling 4 inches per second hits the ground first. I say this out of common sense though, so I am wondering if there is any mathematical way to figure this out? b) No idea how to solve for this as we can't use physics equations.
