The vertical displacement y(x, t) of a string stretched along the horizontal x-axis is given by y(x, t) = (6.00 mm) cos[(3.25 m-1)x - (7.22 rad/s)t]. (a) what is the minimum time for each complete cycle of the wave? (b) what is the distance between adjacent crests of the wave? (c) how fast does this wave travel?

Aplane takes off from an airport and flies to town a, located d1 = 215 km from the airport in the direction 20.0° north of east. the plane then flies to town b, located d2 = 230 km at 30.0° west of north from town a. use graphical methods to determine the distance and direction from town b to the airport. (enter the distance in km and the direction in degrees south of west.)
