If any object is travelling at a constant acceleration i.e. 5m/s/s then the distance covered by that object after 4s as per the formula S=ut+0.5att is 40m but if I calculate the same through v=u+at the same is coming to 50m.

Dear Swarnendu Sengupta,


Ans:- I think you want a long walk in fresh air. It would refresh your mind and you will not do silly mistakes again.


S=0.5×5×4²=40 m   OK


Then v=0+(5×4)=20m/s


Let the ditance travelled by it is=X


v²=u²+2fX


20²=0+(2×5)X


X=40m


Hence X=S UNDERSTOOD ?
