Engineering Mechanics - Dynamics Chapter 14 * Problem 14-88 The Raptor is an outside loop roller coaster in which riders are belted into seats resembling ski-lift chairs. If the cars travel at v 0 when they are at the top of the hill, determine their speed when they are at the top of the loop and the reaction of the passenger of mass M p on his seat at this instant.The car has a mass M c . Neglect friction and the size of the car and passenger. Given: M p 70 kg = M c 50 kg = v 0 4 m s = h 12 m = ρ 5m = g 9.81 m s 2 = Solution: 1 2 Mv 0 2 Mgh + 1 2 1 2 Mg 2 + = v 1 v 0 2 2 gh 4 g + = v 1 7.432
