Question

A body starts from rest and is uniformly accelerated for 30 s. The distances travelled in the first 10 s, next 10 s and last 10 s are x₁, x₂ and x₃. Then x₁:x₂:x₃ is:

G1 Physics · Accepted Answer

For motion from rest with constant acceleration, distances in successive equal time intervals are proportional to 1:3:5. Therefore x₁:x₂:x₃=1:3:5. Hence option C.
