Finding the Acceleration of a Moving Bus Using Newton's Laws

AI Thread Summary
The discussion revolves around a physics problem involving a hammer hanging from a bus's ceiling, where the bus is moving in a straight line. The key to solving the problem lies in analyzing the forces acting on the hammer and applying Newton's second law. The angle of 74 degrees indicates the relationship between the forces due to the bus's acceleration and gravity. The original poster, Tedi, successfully solved the problem after initially seeking help. The interaction highlights the importance of understanding Newton's laws in practical scenarios.

Hello,
Could anyone help me with this problem?

"A hammer is hanging by a light rope from the ceiling of a bus. The ceiling of the bus is parallel to the roadway. The bus is traveling in a straight line on a horizontal street. You observe that hammer hangs at rest with respect to the bus when the angle between the rope and the ceiling of the bus is 74 degrees. What is the acceleration of the bus?"

Thank you very much

To get help, show us what you've come up with so far. (Hint: Analyze the forces acting on the hammer. Use Newton's 2nd law.)
 
ohhh OMG I have just solved it :smile: Why did it take me soo long... Thanks anyway:P
 

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...
