ue and Jenny kick a soccer ball at exactly the same time. Sue’s foot exerts a force of 74.8 N to the north. Jenny’s foot exerts a force of 88.1 N to the east.
a) What is the magnitude of the resultant force on the ball?
b) What is the direction of the resultant force (measured from East)?

If you draw the vectors in a x-y coordinate system and the tail of these vectors at the origin, then, making North your positive y-axis and east your negative x-axis,

the magnitude is the square root of the sum of the squares of these vectors:

Magnitude F = ( (Fx)^2 + (Fy)^2 )^(1/2)

F = ( (-88.1)^2 + (74.8)^2) ^(1/2)

F = 115.57 N

the angle of the direction would be

angle = arctan (Fy / -Fx)

angle = 1.14 degrees measured from the negative x-axis or east.

I hope this helps, good luck.
