Horizontal component of the superhero’s displacement?

AI Thread Summary
The discussion focuses on calculating the horizontal and vertical components of a superhero's displacement while flying at an angle of 22 degrees below the horizontal. The horizontal component is determined to be 315 meters. To find the vertical component, it is necessary to use the sine function with the angle adjusted to -22 degrees. The correct method involves calculating the magnitude of the vector first and then applying the sine function to find the vertical displacement. The calculations emphasize the importance of understanding trigonometric functions in resolving vector components.

1.A superhero flies 340 m from the top of a
tall building at an angle of 22 ◦ below the
horizontal.
What is the horizontal component of the
superhero’s displacement?
Answer in units of m. What is the vertical component of the super-
hero’s displacement?
Answer in units of m.




2. Sin A, Cos A, Tan A



3. The horizontal component is 315m.

How do i find the vertical component?

you use sine instead of cosine. make sure you plug in -22 degrees, though, since the angle given is "below the horizontal"
 


to find the vertical. do i just do (sin -22) and then multiply that by the horizontal component (315)?

no.

you need to find out what the magnitude of the vector is and then find the y component by multiplying it by sine.

Can you write out the equation that gives the x-component? with that equation, do you think you could solve for the original magnitude given an x-component and an angle?

well i found the horizontal component by putting Cos(22) and then i multiplied that answer with the 340m
 
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'
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...
