A body oscillates with simple harmonic mo- tion along the x-axis.

Its displacement varies with time according to the equation

x(t) = A sin(ω t + φ) .

If A = 5 m, ω = 3.799 rad/s, and φ = 1.0472 rad, what is the acceleration of the body at t = 2 s? Note: The argument of the sine function is in radians rather than degrees.

Answer in units of m/s2.

For a certain transverse wave, the distance between two successive maxima is 1.22 m and eight maxima pass a given point along the direction of travel every 10.8 s.

Calculate the wave speed. Answer in units of m/s.
