Part of a wheel coaster ride related. coasting down the incline and enter a loop. 6.40 m diameter. For safety considerations. Speed coaster's wheels at the top of the loop will have a seat in what force of equal size in the weight of what. From those above the bottom of the loop must. Coaster wheel down to meet this need.

At the top of the double-loop centrifugal acceleration to gravitational acceleration down. Are forced to write in the same seat. / Her weight. Therefore V acceleration. He ^ 2 / R = 2G where R is the radius of the circle. (3.2 meters), G is gravity (9.81 m / sec ^ 2) and. V is the speed of a wheel coaster at the top of the loop. From this we will have V = (2GR) ^ 1 / 2. Now calculated. h height net wheels have a coaster. Under gravity to speed. The V h = V ^ 2/2G. And we have these equations. h = R.
