Answer:

234.64 m

Explanation:

Using the formula for calculating range;

Range R = u√2H/g

u is the speed = 13m/s

H is the maximum height

g is the acceleration due to gravity = 9,8m/s²

R = 90m

Get the maximum height;

90 = 13√2H/9.8

90/13 = √2H/9.8

6.923 = √2H/9.8

square both sides

6.923² = 2H/9.8

469.698 = 2H

H = 469.698/2

H = 234.64

Hence the top level was 234.64 m high.
