Position and Displacement question.

AI Thread Summary
To determine net displacement, the starting point is the school, which is located between the store and the house. The store is 750 m south of the school, while the house is 625 m north. The net displacement from the school to the house is calculated as 625 m north, resulting in a total displacement of 625 m in the positive direction. It's important to note that displacement is a vector quantity, requiring both magnitude and direction for a complete answer. Thus, the final net displacement is 625 m north.

Homework Statement


You walk to the corner store after school to buy a carton of milk before going home. The store is 750 m south of the schoo, and your house is 625 m north of the school. What is your net displacement.


Homework Equations



dT=d1+d2

formula for displacement


The Attempt at a Solution



625-750
= -125

I do not think this is right. Please help!

No, it isn't. The first thing you need to do is review the meaning of "net displacement". You started at school and wound up at home. How far from your starting point are you?
 
From school to home I am 625 m away.
 
hi ybhathena! :smile:

then that's the answer! :biggrin:

(except that displacement is a vector, so you need to specify the direction also :wink:)
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
