A body starts from rest and is uniformly accelerated
P for \( 30 \mathrm{~s} \). The distance travelled in the first \( 10 \mathrm{~s} \) is \( \mathrm{x}_{1} \), next \( 10 \mathrm{~s} \) is \( x_{2} \) and the last \( 10 \mathrm{~s} \) is \( x_{3} \). Then \( x_{1}: x_{2}: x_{3} \)
W is the same as
(1) \( 1: 2: 4 \)
(2) \( 1: 2: 5 \)
(3) \( 1: 3: 5 \)
(4) \( 1: 3: 9 \)
