a sprinter applied a force of 200 n in vertical direction and 225 n in the horizontal direction. what was the resultant force acting on his com and at what angle given these forces



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.
