Document Summary

A 0. 450 kg block resting on a frictionless horizontal surface is attached to a spring whose constant force is 45. 0 n/m. A simple pendulum has a mass of 0. 250 kg and a length of 1. 50 m. it is displaced through an angle of 15. 0 and then released. String 1 in the figure has linear density 2 g/m and string 2 has linear density 4 g/m. A student sends pulses in both directions by quickly pulling up the knot and then releasing it. Question 4. (chapter 17: an ambulance with siren emitting a sound of frequency 1000 hz moves away from you towards a cliff at a speed of 10. 0 m/s. In the arrangement shown below, an object can be hung from a string (with linear mass density = 0. 002 00 kg/m) that passes over a light pulley. A tuning fork with a frequency of f = 512 hz is placed near the top of the tube shown below.
