You are watching a series of waves pass by you. You notice that a wave passes by you every 0.806 seconds and that there are 34.6 meters between each crest. How many waves will pass by you each second? How fast are these waves moving?

Why does the equilibrium position of the spring change when a mass is added to the spring? will the mass oscillate around the new equilibrium position of the spring or the previous position without a mass attached to the spring? if the equilibrium position of the spring changes by 20 cm (assuming no initial mass) when a mass is added to the spring with constant 4.9 kg/s^2, what is the mass of the object attached to the spring?
