In order to go stop the coaster at the end of its course, a spring has been installed. When the coaster stops, it stands at 2 m from the ground. If the total distance of the ride is 750 m, the friction is 500 N as before, the spring constant of the spring is 18400 N/m, and the coaster has a speed of 7 m/s at point A, find the amount (extension of spring) by which the spring is compressed when the coaster is brought to a stop.
