Q. A distant 546 Hz tuning fork produces a plane sound wave that moves along the positive x-axis and has an amplitude of 1.05*10^-8 m. write an expression for the displacement as a function of x and t.

Q. Standing on the ground 3.5 from the wall of a building, you want to throw a package from your 1.6 shoulder level to someone in a second-floor window 4.5 above the ground.

1) At what speed should you throw the package so it just barely reaches the window?

2)At what angle should you throw the package so it just barely reaches the window?
