1. The problem statement, all variables and given/known data I am investigating how much force (F) a person of a certain mass (m) would need to go down one of the world's tallest waterslides, "Killimanjaro" for an important maths project. Waterslide height: 49 m Maximum speed: 25.28 m/s 2. Relevant equations I feel like I am not taking enough factors into account. Should I look at the water's drag force, using the equation: R = 0.5 p C A v^2 R = drag force p = density C = coefficient of drag A = acceleration v = velocity 3. The attempt at a solution I am sorry that this is messy however, I tried to find the acceleration by rearranging the "suvat" equation v=u+at. I got 6.52 ms^-2. Next, I placed my value for a (6.52) in the equaiton F=ma (force = mass x acceleration). So that I can find any force, I just need to add the mass of the person within the equation. I think that I need to also take the drag force from the water into account though.
