Plz somebody help, plz this is important. where are the geniuses out there please help. Thanks in advance . Four forces act as shown in the
diagram below, calculate their
resultant.
12N
10N
40
30
60°
15N
9N

i

The resultant vector force = 6.96i - 9.27j

The magnitude = 11.6N

The direction= -53.1 °

Explanation:

i= 10×cos(30) + 15×cos(-60) + 9×cos(-90) + 12×cos(140) = 6.96

j= 10×sin(30) + 15×sin(-60) + 9×sin(-90) + 12×sin(140) = -9.27

explanation:

wind is defined by the direction it blows from.   for example, a wind blowing from north to south is called a northerly wind.
