A football player runs for a distance d₁ = 8.27 m in 1.4 s, at an angle of θ = 51 degrees to the 50-yard line, then turns left and runs a distance d₂ = 12.61 m in 2.18 s, in a direction perpendicular to the 50-yard line. The diagram shows these two displacements relative to an x-y coordinate system, where the x axis is parallel to the 50-yard line, and the y axis is perpendicular to the 50-yard line.

a) What is the magnitude of the total displacement, in meters?

b) What angle, in degrees, does the displacement make with the y axis?

c) What is the magnitude of the average velocity, in m/s?

d) What angle, in degrees does the average velocity make with the y axis?
