Calculating Distance Traveled with Uniform Acceleration

AI Thread Summary
To calculate the distance traveled by a ball rolling down a hill with uniform acceleration, it's essential to understand the relationship between distance, time, and acceleration. Given that the ball travels 180 m during the second 4.4 seconds of its motion, one can use kinematic equations to determine the distance covered in the first 4.4 seconds. The total distance traveled can be derived by analyzing the acceleration and the time intervals. The problem emphasizes the need for a clear understanding of motion under uniform acceleration. Solving this will provide insights into the ball's initial velocity and acceleration.

The attempt of a solution is actually the question. :)
Do you have any idea ?
 
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'
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'
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...
