Cars, Ropes, Forces and Bisecting Angles

AI Thread Summary
The discussion revolves around a physics problem involving a car being pulled out of the mud by two ropes, each exerting a force of 3500 Newtons at a bisected angle of 34.0°. The original poster struggled with applying trigonometry and motion equations to determine the equivalent force of a single rope. After receiving assistance, they realized the problem required calculating the net force of the two applied forces. The issue was resolved, and the poster acknowledged their misunderstanding. The thread concludes with the problem being marked as solved.

Homework Statement


A car is being pulled out of the mud by two forces that are applied by the two ropes shown in the drawing. The dashed line in the drawing bisects the = 34.0° angle. The magnitude of the force applied by each rope is 3500 Newtons.

(I attached the image...)

How much force would a single rope need to apply to accomplish the same effect as the two forces added together?
N



Homework Equations


F= ma


The Attempt at a Solution



I've tried to use trigonometry, although I don't believe that is the right approach. I can't figure out how any of the motion equations play into this, or how to use the F= ma approach. For some reason I don't even know how to begin the problem. I've tried some of the approaches I just listed, but all give me odd answers. Does anyone have any suggestions??

Thank you so much in advance.

this problem is basically asking for the net force of the two forces
 
Sorry, I managed to get help from another person before, but forgot to label is 'SOLVED'. (I know the Solved action itself is not working, but I've decided to label them anyway.)

But thank you! I realize what I was doing wrong.

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}...

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...
