A lооp-the-lоop rollercoаster cаr with mаss (including passengers) of 4200 kg starts from at the top of the 32-m-tall hill (height H in the diagram). At the base of the hill, it travels around a circular loop of radius 12 m (R in the diagram). Assume the track is frictionless and air resistance can be neglected. Determine the speed of the car at the top of the loop. Use g = 9.80 m/s2.
