Vector Addition Using Unit Vector Notation

AI Thread Summary
To solve the problem of finding the x, y, and z components of the sum of two displacement vectors, the components cx = 7.9, cy = -4.0, cz = -6.2 and dx = 4.5, dy = -1.5, dz = 3.3 need to be added together. The sum can be expressed in unit vector notation as A = (cx + dx)i + (cy + dy)j + (cz + dz)k. The discussion highlights confusion regarding the initial steps and the usefulness of hints provided by WileyPlus. Understanding vector representation in unit vector notation is essential for completing the task. Clarifying these concepts will aid in successfully solving the problem.

Homework Statement



Find the (a) x, (b) y, and (c) z components of the sum of the displacements and whose components (in meters, m) along the three axes are cx = 7.9, cy = -4.0, cz = -6.2; dx = 4.5, dy = -1.5, dz = 3.3.

Homework Equations



I don't know.

The Attempt at a Solution



No idea how to even begin this one... WileyPlus gave me a hint, but this hint is pretty much useless.

I didn't wait until the last minute to do these problems, its just that this is the last one on Wiley that i need to do to get above a 9/10...

Looks like you are adding 2 vectors C and D using unit vector notation. Are you familiar with representing a vector A like this: A = axi + byj + cz k?

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...
