1) A man flies a small airplane from Fargo to Bismarck, North Dakota—a distance of 180 mi. Because he is flying into a head wind, the trip takes him 2 h. On the way back, the wind is still blowing at the same speed, so the return trip takes only 1 h 15 min. What is his speed in still air, and how fast is the wind blowing? a. what is the speed (mph) in still air? b. wind speed (mph)? 2)A boat on a river travels downstream between two points, 60 mi apart, in 1 h. The return trip against the current takes 2 1/2 hours. a. What is the boat's speed (in still water)? b. How fast does the current river flow?

I need help with Q4. I can't figure out what equation I should use to find the velocity. I think it would be a combination of the velocity formulas for x and y but I'm not sure. My 4 simplified equations are: 1. Vxf = Vxi 2. (delta)x = Vxi * (delta)t 3. Vyf = 9.8 m/s^2 * (delta)t 4. (delta)y = 1/2(9.8 m/s^2) * (delta)t^2 For my data I have: (delta)y = 0.6604 meters (delta) t = 0.367 seconds I don't need the answer or a long explanation, I really just can't figure out what equation/formula I need to use to find "the velocity of your object as it rolls off the incline and enters free-fall."
