Unformatted text preview: Does this equation help? Not too much – we don’t really have time involved here. Probably better to use a different one. Which one? Now we know how fast it is going when it hits the water. Can I use: No!! a is not a function of ds. We have acceleration as a function of velocity, so I have to integrate with respect to velocity. That means I have to use one of these equations: dt dv a = vdv = ads Which one can I use? Set it up. … Since it asks for a distance, we will want to use ads = vdv. What equation will I use now? Solve Given: Find: a(v), v f = 2 ft/s, v xi =100 mph, h= 200 ft s Sketch Solution:...
