This is going to be long... You have to use s=ut + 1/2at^2 to find acceleration first, which will be 120m/s^2 then use v=u+at to find v after 120m, now again use s=it wala formula to find acceleration in another 260m portion, then again use v=u+at and that's all! You will get v=-100m/s at last, answer was already posted, so all I can do is comment the solution! Keep doing Hard Work!
Yeh dono formulae pehle 1st 120m mein lageinge, fir dobara next 260m mein!
Still any confusion make sure to comment
