Question

If r = at2

and s = 2at, the relation among s, r and a ​

Answer 1

Answer:

Step-by-step explanation:

r  =  at2

s  =  2at

r/s  =  at2/2at

r  =  1/2st

Answer 2

Answer:

s^2 = 4ar

Step-by-step explanation:

Given,

r = at^2 ........(1)

s = 2at .........(2)

From equation (2)

t = s/2a

Now putting the value of (t=s/2a) in equation (1)

Therefor : r = a ( s/2a)^2

r = a * s^2 / 4a^2

r = s^2/4a

ANS : s^2 = 4ar.
