Problem 4. What is the period of a 1.00 m long pendulum?
Problem 5.
(a.) What is the effect on the period of a pendulum if you double its length?

Problem 6.
(a.) What is the maximum velocity of an 85.0 kg person bouncing on a bathroom scale having a force constant
of 1.50 × 106 N/m, if the amplitude of the bounce is 0.200 cm? Assume their bouncing motion is periodic
and can be described as simple harmonic motion.
(b.) What is the maximum energy stored in the spring?
