A football player runs for a distance d, = 8.67 m in 1.25 s, at an angle of e = 57.3degrees to the 50-yard line, then turns left and runs a distance d, = 12.52 m in 1.51 s, ina direction perpendicular to the 50-yard line. The diagram shows these twodisplacements relative to an x-y coordinate system, where the x axis is parallel to the50-yard line, and the y axis is perpendicular to the 50-yard line.What is the magnitude of the total displacement, in meters?What angle, in degrees, does the displacement make with the y axis? (Note that theangle e was given as measured from the x axis rather than the y axis.)What is the magnitude of the average velocity, in m/s?What angle, in degrees does the average velocity make with the y axis? (Note that theangle 0 was given as measured from the x axis rather than the y axis.)

Draw a diagram for the given problem. Here, d is the total displacement, ϕ is the angle made by…
