Unformatted text preview: soto (rrs946) Homework 8 Spurlock (41003) 1 This print-out should have 30 questions. Multiple-choice questions may continue on the next column or page find all choices before answering. 001 (part 1 of 2) 10.0 points A piston in an automobile engine is in simple harmonic motion. Its amplitude of oscillation from the equilibrium (centered) position is 7 . 93 cm and its mass is 1 . 092 kg. Find the maximum velocity of the piston when the auto engine is running at the rate of 2880 rev / min. Answer in units of m / s. 002 (part 2 of 2) 10.0 points Find the maximum acceleration of the piston when the auto engine is running at this rate. Answer in units of km / s 2 . 003 (part 1 of 2) 10.0 points A spring with a spring constant of 1 . 6 10 2 N/m is attached to a 1.6 kg mass and then set in motion. What is the period of the mass-spring sys- tem? Answer in units of s. 004 (part 2 of 2) 10.0 points What is the frequency of the vibration? Answer in units of Hz. 005 10.0 points A 31 . 6 g mass is attached to a horizontal spring with a spring constant of 5 . 35 N / m and released from rest with an amplitude of 29 . 2 cm. What is the velocity of the mass when it is halfway to the equilibrium position if the surface is frictionless? Answer in units of m / s. 006 10.0 points Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1 . 88 m and finds that it makes 309 complete oscillations in 704 s. The amplitude of the oscillations is very small compared to the pendulums length. What is the gravitational acceleration on the surface of this planet? Answer in units of m / s 2 ....
