we have the formula - S = U + a/2(2N-1) [ WHERE U = INITIAL SPEED , & N = value of TIME IN Tth SECOND . ]

so using the formula ------


h/2 = u + a/2(2t-1)


h/10 = 2t-1 { u=0 & a=10}


t = h+10/20


so, total time = h+10/20

now by formula = h=ut + 1/2at^2, (u=0 a=10)




on solving - h = 58.28 metres.
