4.3.9 solution:

def find_net_force_from_file(forces):

total_horizontal = 0

total_vertical = 0

for force in forces:

magnitude=force

angle = force

angle = radians(float(angle))

horizontal = magnitude * cos(angle)

vertical = magnitude * sin(angle)

total_horizontal += horizontal

total_vertical += vertical

net_magnitude = sqrt(total_horizontal**2 + total_vertical**2)

net_magnitude = round(net_magnitude, 1)

net_angle = atan2(total_vertical, total_horizontal)

net_angle = degrees(net_angle)

net_angle = round(net_angle, 1)

return (net_magnitude, net_angle)
