Given that mass of the object is, m= 575 kg
Also velocity of the object, v= 18 m/s
According to law of conservation of energy,
[tex]\begin{gathered} \text{mgh}=\frac{1}{2}mv^2 \\ gh=\frac{1}{2}v^2 \end{gathered}[/tex]Here, g is acceleration due to gravity whose value is 9.8 m/s^2.
So the height, h will be
[tex]h=\frac{v^2}{2g}[/tex]Substituting the values, we get
[tex]\begin{gathered} h=\frac{(18)^2}{2\times9.8} \\ =16.53\text{ m} \end{gathered}[/tex]So the toadstool is 16.53 m high.
