Exercises on Oscillations and Waves Exercise 1 - CPP
Exercises on Oscillations and WavesExercise find a spring in the laboratory. When you hang 100 grams at the end of the springit stretches 10 cm. You pull the 100 gram mass 6 cm from its equilibrium position andlet it go att= 0. Find an equation for the position of the mass as a function of first find the period of the Oscillations , then we can obtain an equation forthe motion. The periodT= 2 m/k. The massmis Kg. To findk, we use thefact that 100 grams causes the spring to stretch an additional 10 cm. SinceF=k x,we havemg=k ( ) =k( )k= period of the motion is thereforeT= 2 Att= 0 themass is at its maximum distance from the origin.
Exercises on Oscillations and Waves Exercise 1.1 You nd a spring in the laboratory. When you hang 100 grams at the end of the spring it stretches 10 cm. You pull the 100 gram mass 6 cm from its equilibrium position and let it go at t= 0. Find an equation for the position of the mass as a function of time t.
