1.You are riding on a 20m diameter Ferris wheel. when your cart is at the bottom, you feel twice as heavy as you normally are. what is the speed of the wheel?

Answer 1

V^2/R = g
Solve for V
g is the acceleration of gravity.

Most Ferris wheels don't go that fast. If they did, you would feel weightless at the top. People would not like that - other amusement park rides can offer that experience.
