Figure P3.40 illustrates typical proportions of male (m) and female (f) anatomies. The displacements d S 1m and d S 1f from the soles of the feet to the navel have magnitudes of 104 cm and 84.0 cm, respectively. The displacements d S 2m and d S 2f from the navel to outstretched fingertips have magnitudes of 100 cm and 86.0 cm, respectively. Find the vector sum of these displacements d S 3 5 d S 1 1 d S 2 for both people.
Chapter 3 Notes When the mass on a spring is set into oscillation, it also pulls on the end of the elastic cord secured to it creating waves Because a mass on a spring performs perfect SHM, waves are periodic both in time and space Almost all waves, except for electromagnetic (light, radio, TV), should have a medium to travel through The particles of elastic medium (air, water, cord) are set into motion while the wave is going through the medium If you excite waves, the particle does not move along with the entire wave, instead, it moves back in forth in the same place is was displaced in The type of wave s categorized by the character of motion of a particle in it Transversal Waves Particles oscillate perpendicular to the direction of the propagation of a wave
