4.) Oscillations a.) A 1.50 kg mass oscillates at 5.50 Hz on a spring with an amplitude of 3.40 cm. Determine the period, the spring constant, and the maximum speed of the mass. b.) A simple pendulum is made by suspending a 450-gram point mass from the end of a 1.60-meter long string. The mass is pulled back so that the string makes a 7.0° angle with the vertical. Determine the change in gravitational potential energy of the mass between its initial position and the equilibrium position. Also, find the maximum speed and period of the pendulum. L 8 L c.) A physical pendulum consists of a uniform rod L = 1.50 m long and suspended from one end. What is the period of oscillation? center-of-mass
