AI Thread Summary
To calculate the resultant vector in physics, it's essential to understand the direction of each vector. Vector A is 100 units at 50 degrees, while vector B is 200 units at 270 degrees, which indeed places it on the negative y-axis. The calculations for the resultant vector involve breaking down each vector into its components, with vector B contributing 0 to the x-axis and -200 to the y-axis. The final answers provided for the resultant vector include 139 units at either 62.4 degrees or 297.5 degrees, depending on the reference direction used. The discussion emphasizes the importance of understanding vector orientation and component analysis in solving such problems.

Homework Statement




vector a = 100 units at 50.0 degrees vector b = 200 units at 270 degrees. find r, sketch a,b, r.


The Attempt at a Solution



The part I don't understand is the 270 degrees. Doesn't this cause vector b to lay on the -y axis? I've tried this question and another one like it:

vector a = 10 units at 40 degrees and vector b = 25 units at 180 degrees.

Answers given for

#1: 139 units at 62.4 degrees or 139 units at 297.5 degrees
#2: 18.5 units at 20.4 degrees above -x axis, or 18.5 at 159.7 degrees

This is the first physics class I have ever taken in my life. Help is greatly appreciated!

nevermind, I found a similar question and was able to solve this!

If anyone finds my question:

Bx = 0
By= -200

That should help with the equation.

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...
