Question

1.)A driver on planet Shinlong hangs her car keys from a massless string. The length of this simple pendulum is 1.10 m. The driver soon realizes that she can get the acceleration of gravity on her planet by timing the rate of the keys swinging. She determines the period of the simple pendulum is 5.02 seconds, so what is the acceleration of gravity on this driver's planet?

2.)A thimble press moves up and down in simple harmonic motion with an amplitude of 2.47 cm and a frequency of 10.1 Hz. What is the maximum acceleration of the thimble press?
