Problem 15P

Calculate the average metabolic rate of a person who sleeps 8.0 h, sits at a desk 8.0 h, engages in light activity 4.0 h, watches television 2.0 h, plays tennis 1.5 h, and runs 0.5 h daily.

SolutionStep 1 of 5The standard equation of displacement for the wave travelling in negative x-directionis y(x,t)= A cos(kx+t)..............1Where A is the amplitude , x and y are displacements along x and y - directions, k iswavenumber and is angular frequency.And the given equation is y(x,t)= 5.2 cm cos(5.5 x+ 72t)........2Comparing equation 1 and 2 amplitude,A= 5.2 cm wavenumber k = 5.5 rad/m and angular frequency =72 rad/s
