Ferris wheel question!!! 1. The problem statement, all variables and given/known data A common amusement park ride is a Ferris wheel (not drawn to scale). Riders sit in chairs that are on pivots so they remain level as the wheel turns at a constant rate. Assume the usual coordinate system (x to the right, y up, z out of the page, toward you.) A particular Ferris wheel has a radius of 22 meters, and it makes one complete revolution around its axle in 20 seconds. In all of the following questions, consider this location (at the center of the axle) as the location around which we will calculate the angular momentum. At the instant shown in the diagram, a child of mass 38 kg, sitting at location F, is traveling with velocity < -6.9, 0, 0> m/s. (location F is at the very bottom of the Ferris wheel "lowest point" I could not get the pic to get on here) What is the momentum of the child? = < -262.2, 0, 0 > kg·m/s ##I already found this already and it is right the next part is where my question is. In the definition L = r x p what is the vector r ? r = <??, ??, 0 > m need to find x and y the r here has an arrow above it What is r perpendiculat? r = 22 m i found this as well really just ned the x and y of r (has arrow above it) 3. The attempt at a solution i found p from above. used La = r x p La i said was m x r perpendicular so 38 x 22 got 836 then did 836 = r x -262.2 then got r = -3.188 but that does not sound right any help would be great.
