A train accelerates from rest at a constant rate α a for distance `x_(1)` and time `t _(1)`. After that is retards at constant rate `beta` for distance `x_(2)` and time `t_(2)` and comes to the rest. Which of the following relation is correct:-

A

x1/x2 = α/ β= t1/t2

B

x1/x2 = β/ α = t1/t2

C

x1/x2 = β/ α = t2/t1

D

x1/x2 = α/ β = t2/t1

Text Solution

Verified by Experts

The correct Answer is:
(i) A, B (ii) A, B (iii) B, A (iv) same (v) B, A, once
By observing the graph, position of A (Q) is greater than position of B (P) i.e. B lives farther than a and also the slope of x-t curve for A & B gives their velocities `v_(B) gt v_(A)`
