Resolving forces of a particles in equi

AI Thread Summary
Forces of 4N, 5N, and 8N act on a particle at bearings of 000°, 090°, and 210°, respectively. To find the resultant force, the forces must be broken down into their components using trigonometric functions. The equation F = Fx + Fy is essential, where Fx and Fy represent the horizontal and vertical components of the forces. A diagram can aid in visualizing the components and their directions. Ultimately, summing the components will yield the magnitude and bearing of the resultant force.

The Attempt at a Solution




I think that the resultant force is in between the 4N and the 5N forces. However I am not sure as i guessed that. I am not sure what to do next.


Plz help
Thanks

Force is a vector therefore has magnitude and direction. Break the forces into its components.

how?
 
http://www.glenbrook.k12.il.us/gbssci/phys/Class/vectors/u3l3b.html . I would show how to resolve forces but I would need to draw a diagram...

right F = Fx + Fy where Fx = Fcos(theta) + FSin(theta) relative to the coordinate system. Once you find all the components you can add all the Fx's and Fy's
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Variable mass system : water sprayed into a moving container'

Starting with the mass considerations #m(t)# is mass of water #M_{c}# mass of container and #M(t)# mass of total system $$M(t) = M_{C} + m(t)$$ $$\Rightarrow \frac{dM(t)}{dt} = \frac{dm(t)}{dt}$$ $$P_i = Mv + u \, dm$$ $$P_f = (M + dm)(v + dv)$$ $$\Delta P = M \, dv + (v - u) \, dm$$ $$F = \frac{dP}{dt} = M \frac{dv}{dt} + (v - u) \frac{dm}{dt}$$ $$F = u \frac{dm}{dt} = \rho A u^2$$ from conservation of momentum , the cannon recoils with the same force which it applies. $$\quad \frac{dm}{dt}...
