Answer :
320 N is the resultant force acting on his com and at 180° angle is given these forces.
F1=200 N
F2=250 N
F resultant=[tex]\sqrt{200^2+250^}[/tex] = [tex]\sqrt{40000+62500}[/tex]
Fr=320 N
Fr=[tex]\sqrt{F_1^2+F_2^2+2F_1F_2 cos\theta}[/tex]
cosФ=fr/f1f2
cosФ=0
[tex]\theta=180[/tex]
In mechanics, a force is any action that seeks to preserve, modify, or deform a body's motion. Isaac Newton's three principles of motion, which are outlined in his Principia Mathematica, are frequently used to illustrate the idea of force (1687).
Newton's first law states that unless a force is applied to a body, it will stay in either its resting or uniformly moving condition along a straight path. According to the second law, when an external force applies on a body, the body accelerates (changes velocity) in the force's direction.
