We use the equations of motion S = ut+(1/2)gt2 and v = u+at
first 5 seconds:- h1 = (1/2)g(25) = 12.5 g, v1 = 5g
h1 is the distance travelled in 5 seconds and v1 is velocity at the end of 5 seconds. initial velocity is zero
next 5 seconds:- h2 = 5g(5) + (1/2)g(25) = 37.5 g, v2 = 10g
h2 is the distance travelled in next 5 seconds and v2 is velocity at the end of 10 seconds
nextt 5 seconds:- h3 = 10g(5)+(1/2)g(25) = 62.5 g, v3 = 15g
h3 is the distance travelled in next 5 seconds and v3 is velocity at the end of 15 seconds
we can find the relation as h3 = h1+h2+12.5g;
