Angry Birds in Exam Question

[clan_NEt]

Angry Birds used as an example in an exam question. The Angry Birds craze continues. We find it everywhere - we have it as soft toy, on keychains ,casings and now it's on as an exam question.

S= ut + .5at^2 = 2m
u = 13.0625

tan@= 13.0625 / (55/2.5)
@= 30.69972

Hence launch angle = 30.7

 

[Admin]

let x = 55 = vCOS@(t)

let y = 2 = vSIN@(t)

y/x = tan @

launch angle = @ = tan^-1 2/55 = 2.0826

 

[clan_NEt]

Which is the correct answer?!

 

[jusclickaway]

wtffff. i cant even answer. now i know the admin and moderator are smart ppl.

 

[prosu]

Sinful's answer is based on several assumptions. Never include air resistance and all

 

[thecakeisalie]

seems like a tough question

 

[Admin]

let x = 55 = vCOS@(t)

let y = 2 = vSIN@(t)

y/x = tan @

launch angle = @ = tan^-1 2/55 = 2.0826

Just realised my answer is wrong. I did not take into account gravitational acceleration. Sinful's answer shd be correct.
