Example 7. Find the components of the 240-N<br />
force exerted by the boy on the girl if his arm<br />
makes an angle of 28 0 with the ground.<br />
F y<br />
F = 240 N<br />
F<br />
28 0<br />
F y<br />
F x<br />
F x = -|(240 N) cos 28 0 | = -212 N<br />
F y = +|(240 N) sin 28 0 | = +113 N<br />
Or in i,j notation:<br />
F = -(212<br />
N)i + (113 N)j
