Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points The motion of a piston in an auto engine is simple harmonic. The piston travels back and forth over a distance of 9 . 1 cm, and the piston has a mass of 2 . 4 kg. 4991 rpm 9 . 1 cm What is the maximum speed of the piston when the engine is running at 4991 rpm? Answer in units of m / s. 002 (part 2 of 2) 10.0 points What is the maximum force acting on the piston when the engine is running at the same rate? Answer in units of N. 003 10.0 points The mass of the deuterium molecule D 2 is twice that of the hydrogen molecule H 2 . If the vibrational frequency of H 2 is 1 . 21 10 14 Hz, what is the vibrational frequency of D 2 , assuming that the spring constant of attracting forces is the same for the two species?...
