Two vehicles approach an intersection: a truck moving eastbound at 16.0 m/s and an SUV moving southbound at 20.0 m/s. Suppose that the x-axis is directed eastward and the y-axis is directed northward. Find the magnitude of the velocity vector of the truck relative to the SUV. Find the direction angle of the velocity vector of the truck relative to the SUV. The angle is measured from the x-axis toward the y-axis.
a. Magnitude: 28 m/s, Direction angle: 53.13°
b. Magnitude: 36 m/s, Direction angle: 33.69°
c. Magnitude: 10 m/s, Direction angle: 76.89°
d. Magnitude: 24 m/s, Direction angle: 42.38°
