A particle starts moving from position of rest under a constant acceleration. If it travels a distance x in t second, what distance will it travel in next t second? 


Given, 

Initial velocity, u = 0

Distance travelled, s = x

Time taken to travel x distance, t = t sec

Now, using the relation, 

straight s space equals space ut plus space 1 half at squared comma we have
x = 0 + 1/2 at2                     ... (1)

Let the body travel a distance y in next t seconds. 

The total distance travelled in t+t = 2t sec will be (x+y).

Therefore, 

(x+y) = 1/2 a (2t)2

          = 1/2a x 4t2                 ... (2)

Dividing equation (2) by (1), we have

space space space space space space fraction numerator left parenthesis straight x plus straight y right parenthesis over denominator straight x end fraction space equals space 4 space

rightwards double arrow space space space space space space space space space space space straight y space equals space 3 straight x
