Answer:
Ratio = 1:2:3
Explanation:
S = ut + 1/2gt^2
h1 = 1/2 x 10 x 25
h1= 50m
V = u + gt
V1 = 10 x 5
V1 = 50m/s
This will be initial velocity for next 5sec-
V1 = U2
h2 = 50 + 1/2 x 10 x 25 = 50 + 50
h2 = 100m
V2 = 50 + 10 x 5 = 50 + 50
V2 = 100m/s
Similarly, V2 = U3
h3 = 100 + 1/2 x 10 x 25 = 100 + 50
h3 = 150m
Ratios of heights -
h1:h2:h3 = 50:100:150
Ratio = 1:2:3
Hope you can understand it well.
