Question

5. A body. Starting from rest and moving with a constant acceleration, covers a distance Siin the 4 seconds and a distance S, in the 6 seconds. The ratio of S/S, is (b) 4/9 (c) 6/11 (d) 7/ 11​

Answer 1

Answer:

S1/S2 = 7/11

Explanation:

the formula for distance travelled by a body in the second = u+(2n-1) a/2

here initial spred ,u, = 0

therefore,

S1=(2*6-1)a/2

S1/S2 = 7/11

Answer 2

Answer:

Up to 20 sec

Explanation:

if it's moves S1 distance in the first 10 sec, and S2 distance in the next 10 sec then S2
