- Problem 2: Consider that a pilot flies 45 km in a direction 60° north of east and then flies 32 km in a direction 15° north of east as shown in the figure. a) Find her distance R from the starting point in kilometers b) Find the angle in degrees N of EAdd the vectors A and B in the figure using the method of components. The magnitudes of both vectors are 2.55 m, and the angle vector A makes with the x-axis is 0 = 34.5°. Your result should be in unit-vector notation. (Give your answer in terms of meters.) A + B = L mTake two values, say 1 and 2 and use the relationship, (picture)\ Are the values in both sides of the equation the same? What is the difference? Talk about this.
