Multiple-choice questions may continue on the next column or page find all choices before answering. 001 10.0 points A spring stretches 3 . 3 cm when a 16 g object is hung from it. The object is replaced with a block of mass 25 g which oscillates in simple harmonic motion. The acceleration of gravity is 9 . 8 m / s 2 . Calculate the period of motion. Answer in units of s. 002 10.0 points Having landed on a newly discovered planet, an astronaut sets up a simple pendulum of length 1 . 57 m and finds that it makes 302 complete oscillations in 593 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 . 003 10.0 points You need to know the height of a tower, but darkness obscures the ceiling. You note that a pendulum extending from the ceiling almost touches the floor and that its period is 26 s.touches the floor and that its period is 26 s....
