I'm doing the MIT Physics 1 : Classical Mechanics course, offered by OpenCourseware. I'm watching the first lecture and reviewing the slides, and don't seem to understand this question on Dimensional Analysis:
The speed of a sail-boat or other craft that does not plane is limited by the wave it makes – it can’t climb uphill over the front of the wave. What is the maximum speed you’d expect? Hint: relevant quantities might be the length l of the boat, the density ρ of the water, and the gravitational acceleration g.
Here is a link to the question - LINK- It is on slide 15.
Any guidance to help solve this problem will be much appreciated!
