Finding the resultant and eq. for 3 vector on one point

AI Thread Summary
To find the resultant of the three vectors, start by determining their components along the x and y axes using trigonometric functions. For each vector, calculate Ax and Ay, where Ax = A * cos(θ) and Ay = A * sin(θ). Sum the x-components (ΣFx) and y-components (ΣFy) to find the overall resultant vector. Finally, use the Pythagorean theorem to calculate the magnitude of the resultant and trigonometry to find its direction. This method will help clarify the concepts needed for the quiz.

Homework Statement


I need help with this homework problem.
1st vector: 80 N & 180 degree
2nd vector: 40 N & 145 degree
3rd vector: 50 N & -50 degree

And I need to find the resultant and the Eq. Where do I start and how do I do it please include answer as I'm confuse and I have a quiz on this soon. thanks

Hi needhelp 1, welcome to PF.
Do you know how to find the components of a vector along x and y axis?
If you know find the components and find ΣFx and ΣFy. Then find the resultant.
 
Thx for the quick reply! Can you guild me through? I don't understand this chapter. I was sick during the week due to a bad flu.
 
If A is a vector which makes an angle θ with the x axis, what is Ax and Ay?
 

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}...
