AI Thread Summary
The discussion revolves around a physics problem involving a car accelerating on a curve and calculating the number of revolutions based on changing acceleration. The car starts from rest with a radius of 110 m and an acceleration of 1.20 m/s², aiming to determine how many revolutions occur when the total acceleration reaches 2.20 m/s². The original poster expresses confusion about calculating time, distance, and angle during the acceleration change. After some realization, they still struggle with similar problems and seek further assistance. The conversation highlights the complexities of tangential acceleration in rotational motion.

arr, i am so confused, is that tangential accelaration?

Homework Statement


A car starts from rest on a curve with a radius of 110 m and accelerates at 1.20 m/s^2. How many revolutions will the car have gone through when the magnitude of its total acceleration is 2.20 m/s^2?


Homework Equations



theta (final)=theta (initial)+omega*(delta)t+(a*(delta)t^2)/2*r

The Attempt at a Solution



i just have no idea how to figure out the time or the distance (or the angle) it takes the car to get from one acceleration to another...

I am having trouble with a similar problem like this. Any help? I've been using the formulas but I keep getting weird numbers

Thanks
 
feedmeister can you make a new thread please? that way people will know it's your problem since mashawa doesn't need help here anymore.
 

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'

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...
