Projectile Motion & Vectors: Acceleration and Axis Conventions Explained

AI Thread Summary
The discussion focuses on projectile motion, specifically the constant downward acceleration of 10 m/s². Participants confirm that the negative sign in the vertical axis (denoted by j) indicates downward direction. The importance of writing kinematic equations for clarity in solving projectile motion problems is also emphasized. Overall, the key takeaway is the consistent downward acceleration in projectile motion and its representation in vector notation. Understanding these concepts is crucial for solving related physics problems effectively.

The Attempt at a Solution


I know that the acceleration is downward always with value of 10m/s2
The answer is D? because j denote vertical axis and negative sign means downward?

It wouldn't hurt to write down the kinematic equations for the projectile motion in step 2.

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...
