  1. centripetal force CF = m*V^2/r = m*410^2/(3.6^2*2150) =6.033*m weight W = m*g =9.806*m banking angle from vertical = arctan(CF/W) = arctan (6.033/9.806) = 31.34°

  2. (B) mv^2/r = m*6.45*g = (73.0 kg)(9.81 m/s^2)(6.45) = Around 4500 N but use a calculator. (A) v^2/r <= 6.45*g => r >= v^2/(6.45*g) = (103 m/s)^2/(6.45*9.81 m/s^2) = around 15m but use a calculator.

  4. 625km/h * 1m/s / 3.6km/h = 173.6 m/s horizontal (radial, or centripetal) acceleration ax = v²/r vertical acceleration is zero, which means that ay = g where ax and ay are provided by the "lift." ax / ay = tanΘ = v² / gr r = v² / gtanΘ = (173.6m/s)²...

  6. During the time the ball is falling, it has a vertical acceleration of 9.8 m/s^2. Use the following equation to calculate the time. d = vi * t + ½ * a * t^2 Since ball is moving horizontally, its initial vertical velocity...

  7. I agree with your value for centripetal acceleration, but the implication here is that the plane is not following a circular path. Try calculating the acceleration in the original direction of travel as the component of velocity in that direction changes from 217.1 m/s to zero...
