1. The problem statement, all variables and given/known data If the car starts at height h = 60.0 m and the radius is R = 15.0 m, compute the tangential acceleration of the passengers when the car is at point C, which is at the end of a horizontal diameter. Take the free fall acceleration to be g = 9.80 m/s^2. 2. Relevant equations 3. The attempt at a solution Have tried a couple of solutions but have limited chances left. Don't want to get it wrong, any ideas?
