The daughter gets on and swings with frequency f1. Later, the physics teacher gets on the same swing. His frequency is f2. The physics teacher is both taller and more massive than his daughter. 1) Compare f1to f2, and explain why there is a difference.A 50-g mass is attached to a spring and allowed to come to equilibrium. The mass is then pulled 5 cm downward and then released from rest. It oscillates with a frequency of 2.0 Hz. 2) When is the mass first located 2 cm above the equilibrium position? 3) What is the velocity of the mass when it is first located 2 cm above the equilibrium position? 4) The 50-gram mass is replaced with a 125-gram mass. What is its period of the oscillation? On a distant planet, a spring hangs vertically when a mass
