Horizontal component of the superhero’s displacement?

[Thousands]

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
