A body moves from rest with an uniform acceleration and travel 270m in 3s Find the final velocity of the body at 10s after the start |
|
Answer» We knows = ut + 1/2 a. t^2or 270 = 0 . 3 + 1/2 . a. (3)^2Or a= (270 . 2) / 9Or a= 60 m/s^2Again We know that:a = (v - u ) / tOr 60 = (v - 0 )/ 10Or v = 60 . 10∴ v = 600 m/s |
