bhai ji
is the answer correct?
i guess it is 70
please confirm
W.K.T V=U+at. here V=2÷20=10. and t=2 by substituting we get a=5. W.K.T at t seconds v=a×t. by substituting v=5*7=45
yes it is correct
if u got answer 70 then send me the explanation
i have send the explanation please do refer and Eddie the answer!

jhadehari?
no mate u hav to take rest point as 0sec and from that u hav to calculate the velocity after 7sec from that point this is what question meant for
see mate it is up to you how you make the diagram
and the time peon is taken from 2 seconds or can be taken from 0 seconds also but then the diagram will defer but show the same thing
inmeant position instead of poen
anyway buddy from my point of u my ans is correct and from ur side ur ans is correct. anyway nice explanation.
thanks!
have a nice day mate!
