MY NOTES ASK YOUR TEACHER (a) What is the length of a simple pendulum that oscillates with a period of 1.6 s on Earth, where the acceleration due to gravity is 9.80 m/s, and on Mars, where the acceleration due to gravity is 3.70 m/s2? LE = m Module 41- SHM of a Simple Pendulum LM m (b) What mass would you need to suspend from a spring with a force constant of 20 N/m in order for the mass-spring system to oscillate with a period of 1.6 s on Earth, where the acceleration due to gravity is 9.80 m/s, and on Mars, where the acceleration due to gravity is 3.70 m/s?

MY NOTES ASK YOUR TEACHER (a) What is the effect on the period of a pendulum if you double its length? The period would not change. The period is increased by a factor of 2. The period is decreased by a factor of 2. The period is increased by a factor of VZ. The period is decreased by a factor of v 2. (b) What is the effect on the period of a pendulum if you decrease its length by 3.60%? (Answer this question in terms of the initial period T.) T' = Submit
