it was just a "proof", not part of the actual question. I thought since displacement and velocity were correlated with time i could use that fact to "prove" the solution i got.
I get it.
i additionally had a proof where i correlated velocity with displacement and converted all of the components with their respective displacement during the time period. (its definitely wrong because i got the same answer) could you help me fix that as well?
the acceleration would have counteracted an initial component of the initial velocity that was towards the south would it not?
the acceleration doesn't affect the initial velocity to the east so that component still exists which is why the final velocity lies towards the east
I used the average velocity because the final velocity of the acceleration wouldn't be applied to the initial velocity for the entire duration of the 4.11s.
This idea could be misguided and I would like to know if it is and why.
Sorry about the lack of visuals. The question is about trying to solve for an initial velocity when it is accelerated by 2.82m/s2 for 4.11 seconds and whether the final velocity or average velocity should be used as the added component.
Homework Statement
A bird flying in the air accelerates 2.82 m/s2 north for 4.11 seconds. the final velocity of the bird is 9.09 m/s [east]. What was the initial velocity of the bird?
Homework Equations
vf=v0+a*t
v(average)=(v0+vf)/2
v=d/t
d=v0t +½at2
tanθ=opp/adj
The Attempt at a Solution...
Hey all, Christopher here.
I'm currently in grade 12 as of this year and thought that this would be a good way to ask questions for some of the things that I'm unsure of. I want to continue to study physics in the future, so expect me to occasionally post questions asking for help.
