3) The Raptor is an outside loop roller coaster in which riders are belted into seats resembling ski-lift chairs. If the cars travel at vo = (4+0.01*A) m/s 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 70-kg passenger on his seat at this instant. The car has a mass of 50 kg. Take h =( 12+0.02*A) m, p =5 m. Neglect friction and the size of the car and passenger .
