Hi, let's see the mass m equal to 55 kg and f1 equal to 65 newton with teta equal to, let is teta 1 equal to 59 degree and f2 equal to 35 newton with teta 2 equal to 32 degree.
00:22
So f x equal to f1 cos 59 degree plus f2 sine 32 degree into i cap.
00:38
That is equal to 65 cos 59 degree plus 35 sine 32 degree into eye cap.
00:49
That is equal to 52 .025 i cap.
00:55
Similarly, fy equal to f2, cos 32 degree minus f1, sign 59 degree into j cap.
01:10
That is equal to 35 cost 32 degree minus 65, sine 59 degree, into j cap that is equal to minus 26 .034 j cap.
01:29
Now the net force equal to fx plus f y that is equal to 52 .025 i cap minus 26 .034 j cap now the magnitude of net force that is the magnitude of net force that is the magnitude of net force equal to root of 52 .025 square plus minus of 26 .034 square.

That is equal to 58 .1753 newton...
