2. Show that the equation of a traveling wave given as y = a sin (kx - wt) may be rewritten in the
following forms (i) y = a sin k(x - vt)(ii) y = a sin
2π(x/ - xt) (iii) y = a sin w(x/v –t), and (iv) y =
a sin 27(x/2 - 1/T) where the symbols have their usual
meanings.

Arocket starts from rest and moves upward from the surface of the earth. for the first 10.0 s of its motion, the vertical acceleration of the rocket is given by ay = 12.80 m/s32t, where the +y-direction is upward. (a) what is the height of the rocket above the surface of the earth at t = 10.0 s? b) what is the speed of the rocket when it is 325 m above the surface of the earth?
