Question: A very small steel marble is shown rolling at a constant speed on a horizontal table. The marble leaves the table at L, falls, and hits the ground at P. This is illustrated in the diagram below which is drawn to scale.
Part A: Calculate the time it took the marble to travel from N to P.
I'm working on this question out of my book and I'm come to a question that I'm very confused on. I'm not really sure where to even start with it.
