How Do You Calculate Net Displacement in Multiple Directions?

AI Thread Summary
To calculate net displacement in multiple directions, first determine the resultant of the movements. The student runs 30m east and 50m west, resulting in a net movement of 20m west. Next, combine this with the 40m north movement to form a right triangle. The magnitude of the net displacement can be found using the Pythagorean theorem, resulting in approximately 20.0m northwest. Understanding vector addition is key to solving such problems efficiently.

A student runs 30m east, 40m north and 50m west. What is the magnitude of the students net displacement? What is the net displacement?

I can't find an equation to solve this problem. Could someone please give me some guildlines to figure out net displacement of multiple directions?

Can you simplify the sum of these 3 vectors to a sum of 2... Hint: what is the net displacement of 30m east and 50m west.
 

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}...
