Question

A particle starting from rest with constant acceleration Travels a distance x in first 2s and the distance y in next 2s then

Answer 1

Answer: below Explanation

Explanation:

Step-by-step explanation:

A particle starting from rest travels a distance x in first two seconds

Now, The particle travels distance y in next 2 seconds

Now, x = 2a from equation (1)

⇒ y = 3x

Hence Proved.

Answer 2

Answer:

Y = 3X

Explanation:

S = ut + 1/2 at square                               ( S1 = X    S2 = Y

X = 2u + 1/2 a4                                         t1 = 2s    t2 = 2 +2 = 4s)

X = 2u + 2a  

since, u = 0

Therefore, X = 2a...…(1)

Y = (4u + 1/2 a16) -  ( 2u + 1/2 a4)

Y = 4u + 8a - 2u - 2a

Y = 2u + 6a

since, u = 0

Therefore, Y = 6a

here a are equal

a = Y/6

X = 2a

= 2 × Y/6

X= Y/3

Y = 3X
