Question

A Car Starts From Rest And Moves With Constant Acceleration . It Covers Distance 'D' In Time 'T'. What Is Time Taken By The Car To Cover Second Half Portion Of The Journey ?
Kindly answer with full explanation.

Answer 1

3t is the time taken by the car to cover the second-half portion of the journey.

Explanation:

Given,

Car travels with constant acceleration

Distance = D

Time = T

As we know,

s = ut + 1/2at^2 &

d = 1/2at^2

Let 't' be the time for the total journey and the '2d' as the total distance

Now,

2d = 1/2at^2

2d = dt^2 * t^2 * 2t*2

= t^2*t

= 3t
