AI Thread Summary
The discussion revolves around determining the position vector of a mouse at point C, given its starting position and the coordinates of point C. The coordinates of point C are confirmed as (3 m, -5.4 m). The user initially struggled with the correct format for the answer, mistakenly entering values in degrees and meters. Clarification was provided that the position vector should reflect the change in position from the mouse's starting point to point C. The user ultimately understood that the correct approach involves calculating the changes in both the x and y directions from the original position.

Homework Statement


A mouse starts at position (-2 m, 0.5 m), relative to a piece of cheese at the origin, and follows the path shown in the x-y graph below. Find the position vector of the mouse at point C and enter your answer in component form.



Homework Equations


The co-ordianates of point C are (3 m, -5.4m)


The Attempt at a Solution


Well I can't put a picture of the graph up on here, so if there is any information left out that the graph may contain please let me know.

There are 2 answer slots, one for each component of the answer i guess. In my first attempt I entered 8.84m in the first slot and 38degrees in the second (obtained these from constructing a triangle and using trigonometry), but i was told my units must both be meters. So I put in the co-ordinates of the point itself and that is still wrong. Any help would be greatly appreciated

The first component is the x and the second is the y. I'm assuming the path the mouse took was a straight line so basically you compare the points in terms of change in x and change in y. How much did the mouse move in the x direction to get to point C? How much did the mouse move in the y direction to get to point C?

I'm not 100% if this is correct (assumed a straight line) but this seems to be the way to approach the problem.
 
change in x and change in y from where? the origin? Those would just be the co-ordinates of the point C, which i already entered, wouldn't they?
 
No, it is the change from where the mouse orginally started (-2m, .5m).
 
Oh okay thanks! I got it now.
 

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}...
