Three professional wrestlers are fighting over a champion's belt, and each exerts a force on the belt. wrestler 1 exerts a force f1 = 40.0 n in the +x-direction, wrestler 2 exerts a force f2 = 80.0 n in the -y-direction, and wrestler 3 exerts a force f3 = 60.0 n at an angle of 36.9∘ counterclockwise from the +x-direction. find the x- and y-components of the net external force f⃗ on the belt.

The x-component of the net external force Fx = 88.0 N î

The y-component of the net external force Fy = - 44 N ĵ

Explanation:

Net force acting on an object is the sum of all forces acting upon it.

F = F1 + F2 + F3

Forces in terms of x,y-components:  

F₁ = 40 N î             (where î is the unit vector in x-direction)

F₂ = -80 N ĵ             (where ĵ is the unit vector in y-direction)

F₃ = 60 N

= F₃cosθ î + F₃sinθ ĵ

= 60*cos(36.9°) î + 60*sin(36.9°) ĵ

=  48î   + 36ĵ

Net External Force = F1 + F2 + F3

= 40 î - 80 ĵ  + 48 î  + 36 ĵ

= 40 î  + 48 î  - 80 ĵ  + 36 ĵ

= 88 î  - 44 ĵ

Here, only like components(same direction) can be added into each other.

it about 600 mph from what i calculated

the moon affects the earth gravitation ally, causing certain motions of that body and also producing tides in its ocean and atmosphere. the tidal wave in our atmosphere is, however, far too minute to be an effective cause in any known meteorological phenomenon.
