AI Thread Summary
The discussion centers on calculating the component of a jet plane's velocity that is perpendicular to the ground while flying at 500 m/s over a hill with a 3.00% grade. Participants clarify that a 3.00% grade indicates the rise is 3% of the horizontal distance (run), which represents the slope of the hill. The main question is how to set up the problem to find the perpendicular velocity component. Understanding the relationship between the plane's velocity and the slope is crucial for solving the problem. The conversation emphasizes the importance of including units in questions for clarity.

A jet plane is flying horizontally with a speed of 500 over a hill that slopes upward with a 3.00% grade (i.e., the "rise" is 3.00% of the "run").

Hi, i don't understand the part about 3.00% grade. Could someone please help me how to set up, Is that the slope or something?
 
Physics news on Phys.org
Percent grade is a way of expressing slope. If the rise is 3% of the run, what is the slope?

PS: don't forget to include all the units when you post a question; 500 what?
 
ah, it's 500 m/s
 
Now, what was the question?
 
it's asked for
What is the component of the plane's velocity perpendicular to the ground?
 

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...
