Four forces act on an object, given by
A = 47.3 N east,
B = 37.3 N north,
C = 78.7 N west,
and
D = 80.7 N south.
(Assume east and north are directed along the +x-axis and +y-axis,respectively.)
 
(a)
What is the magnitude of the net force (in N) on the object?
 
(b)
What is the direction of the force? (Enter your answer in degrees counterclockwise from the +x-axis.)
