Best ResponseYou've already chosen the best response.0dw:1327065330013:dwhere you first find out the height reached by ball acceleration due to gravity is 10 in the downward direction an addition of 2.5m/s^2 acts in the downward direction so add them both as they say air resitance is a contant force apply equation v^2u^2=2as to find max ht energy=work done (capability) work done=F.s find it!

Best ResponseYou've already chosen the best response.0as they say nonmechanical energy we say work done by air resistance as mechanical energy=k.e+p.e

Best ResponseYou've already chosen the best response.0is the max height 4? because for the final answer i got 50, but thats wrong...

Best ResponseYou've already chosen the best response.0one more thing, so air is non mechanical energy? and huh? i did w=fdcos =2.5 x 4 = 10 ?

Best ResponseYou've already chosen the best response.0ya dont worry abt cos@ as angle here is 180 ie w=2.5*0.04*1

Best ResponseYou've already chosen the best response.0why did you change it to .04? because i used 4 and that got me the right answer?

Best ResponseYou've already chosen the best response.0omg... if youre still there, what is non mechanical energy and how did you know air resistance was it?
