Question

. The ratio of distances traveled by two bodies A and
B starting from rest moving along a straight line with
equal accelerations is x, where x > 1, then
(a) time taken by body A > time taken by body B.
6) time taken by body A < time taken by body B.
(c) time taken by body A 2 time taken by body B.
(d) time taken by body A S time taken by body B.​

Answer 1

The ratio of distances traveled by two bodies A and

B starting from rest moving along a straight line with

equal accelerations is x, where x > 1, then

(a) time taken by body A > time taken by body B.

6) time taken by body A < time taken by body B.

(c) time taken by body A 2 time taken by body B.

(d) time taken by body A S time taken by body B.

Answer 2

Answer:

Given u=0

Let distance travelled by by Bodies A = SA, 

Let distance travelled by by Bodies B = SB,

Let acceleration is a.

Using s=ut+21at2

SBSA=21atb221atA2   ⇒SBSA=tB2tA2=n, 

If n≥1, tB2tA2≥1   ⇒tA≥tB, 

If n=1, tB2tA2=1
