Detailed Solution

A particle experiences constant acceleration for

20 s

after starting from rest. If it travels a distance

X_{1}

, in the first

10 s

and the distance

X_{2}

, in the remaining

10 s

, then

X_{2} = 3 X_{1}

.
We know that

s = ut + \frac{1}{2} a t^{2}

Where,

s =

distance,

u =

initial velocity,

a =

acceleration and

t =

time
Let “

v

” be the velocity at

t = 1

sec
Then for first

10

seconds, as the particle starts moving from rest then

u = 0

Therefore,

X_{1} = 0 \times t + \frac{1}{2} a \times 100

= 50 a

Now after

10

second the velocity becomes

10 a

, by using formula

v = u + at

Therefore,

X_{2} = 10 \times a \times 10 + \frac{1}{2} \times a \times 100

= 150 a

Therefore,

X_{2} = 3 X_{1}
