1) If a mass mm
and a mass 2 oscillate on identical springs with identical amplitudes, they both have the same maximum kinetic energy. How can this be? Shouldn't the larger mass have more kinetic energy? Explain.
2) A) You take your pulse and observe 62 heartbeats in a minute. What
are the period and frequency of your heartbeat? B) If the frequency of your heartbeat increases, will the number of beats in a minute increase, decrease, or stay the same? C) How many beats occur in a minute if the frequency increases to 1.35 Hz.
3) The speed of surface waves in water decreases as the water becomes
shallower. Suppose waves travel across the surface of a lake with a speed of 2.2 m/s and a wavelength of 1.35 m. When these waves move into a shallower part of the lake, their speed decreases to 1.6 m/s, though the frequency remains the same. Find the wavelength of the waves in the shallower water.
