A car in an amusement park ride rolls without friction around the track. It starts from rest at point A at a height h above the bottom of the loop. (a) What is the minimum value of h (in terms of R) such that the car moves around the loop without falling off at the top (point B)? (b) If [tex] h = 3.5R [/tex] and [tex] R = 30 m [/tex] compute the speed, radial acceleration, and tangential acceleration of the passengers when the car is at point C, which is at the end of the horizontal diameter. Show acceleration components in a diagram.(adsbygoogle = window.adsbygoogle || []).push({});

All I know is that at point A, the kinetic energy will be equal to 0. Do I have to use [tex] K_{1} + U_{1} + W_{other} = K_{2} + U_{2} [/tex]? Also does [tex] h = 2R [/tex]

Any help would be appreciated

Thanks
