The following four forces act on 4.00 kg object:
F1 = 300 N east
F2 = 700 N north
F3 = 500 N west
F4 = 600 N south
What is the acceleration of the object?

• Physics! -

resultant N: 100N
reslultantW: 200W

resulatant: sqrt50000 in the direction arctan 2 N of W

acceleration=that force/4kg

100N north and 200N west
100^2+200^2=c^2
10000+40000=c^2
50000=c^2
√50000=c

tanx=200/100
tanx=2
x=arctan(2)
x=63.4 degrees

223.6N, 63.4 degrees west of north.

f=ma
223.6/4=a
55.9m/s^2=a

55.9m/s^2 63.4 degrees west of north.
