I HAVE A TIME LIMIT OF 30 MINUTES PLEASE ANSWER QUICKLY. THANK YOU!A car in an amusement park of mass 300kg, rolls without friction along the length of the recycled rail shown in the figure. It starts at rest from point A and at height h from the lowest point of the circular orbit. If the radius of the circular track is R = 25.0m and the height h = 3.5R, calculate: (a) The speed at which the car moves at the highest point of the circular track (point B} (b) The force exerted by the rail in the car at point B. (c) The speed, radial acceleration, and tangential acceleration of the Passengers when the car is at point C, corresponding to the end of a horizontal diameter, show these accelerations in a diagram.
