Physics homework help (one question)

AI Thread Summary
To solve the problem of average velocity for the bus trip, first calculate the time taken for each segment using the formula time = distance/velocity. The bus travels 320 km at 96 km/h, taking approximately 3.33 hours, and then 230 km at 70 km/h, taking about 3.29 hours, plus an additional 0.42 hours for the 25-minute stop. The total distance is 550 km, and the total time is roughly 7.04 hours. The average velocity is then calculated by dividing the total distance by the total time, resulting in an average velocity of approximately 78.1 km/h. This method effectively combines distance and time to find the average velocity for the entire trip.

I have been having trouble with this one problem... If you could supply me with an answer and possibly a brief description of your methods I would be infinately in your debt:

A bus travels 320 km south along a straight path with an average velocity of 96 km/h to the south. The bus stops for 25 min, then it travels 230 km south with an average velocity of 70 km/h to the south. What is the average velocity for the total trip? Answer in units of km/h.

Thanks in advance

Note: i might be wrong (lol)

first i would add up the times.. so time = distance/velocity. and time for the 25 minutes = 25/60.

and then add up all the distances..

and then average velocity = total distance/ total time.

hope this was helpful!

thank you amy, I am retarted... I love you
 

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 '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...
