Question

A particle is dropped from the top of a tower. during its motion it covers 9/25 part of height of tower in the last 1second . then find the height of the tower​

Answer 1

Answer:125m

Explanation:

Acc. To gallelio odd no. Ratio

1:3:5:7:9......

From above 9/25 i.e{9th part of 25{1+3+5+7+9} as there are 5 numbers from 1 to 9

Takes 5sec

S=1/2*10*25

S=125

Answer 2

Answer:

Explanation:

S(n)= ut +1/2 gt^2

S(n-1) =u(t-1) +1/2g(t-1) ^2

Substract equation 2 from equation 1

Also put u = 0

9/25 H = 1/2 g(2t-1) -----(3)

Also

H=1/2 gt^2

Replace the value of H in equation 3
