The biggest loop is 35 m high, with a maxi- mum speed of 31 m/s (nearly 69.44 mph) at the bottom. Suppose the speed at the top is 11 m/s and the corresponding centripetal acceleration is 2.6 g (where g is the free-fall acceleration). The acceleration of gravity is 9.8 m/s². What is the radius of the arc of the teardrop at the top? Answer in units of m. 022 (part 2 of 4) If the total mass of the cars plus people is 2158 kg, what force does the rail exert on it at the top? Answer in units of N. 023 (part 3 of 4) I Suppose the roller coaster had a loop of radius 14 m. If the cars have the same speed (11 m/s) at the top, what is the centripetal acceleration at the top? Answer in units of m/s². 024 (part 4 of 4) What is the normal force at the top in this situation? Answer in units of N.
