Why might your foot hurt if you kick a heavy desk or a wall?

Step-by-Step Solution:
Step 1 of 3

Physics 2 for Engineering Week 12 Oscillation Power = Energy / time Power is proportional to amplitude 2 Intensity = Power / Area for sound waves Mechanical Waves Needs medium to propagate As opposed to electromagnetic waves propagate in free space (light waves) Transverse wave- string, water; oscillation in y direction, movement in x direction Longitudinal wave- sound; oscillation in same direction as movement Simple Harmonic Motion y = A cos (ω t + ϕ) ϕ is phase constant Wave Equation y= A cos (k x - ω t) Where k is the wave number = 2π/λ Where λ is the wavelength (separation of two crests
