Answer:6.71 m/s

Explanation:

Given

Apple fall from a height of [tex]h=2.3 m[/tex]  

We need to find the impact speed of apple which can be given by using

[tex]v^2-u^2=2gh[/tex]  

where v=final velocity

u=initial velocity

h=Displacement

Assuming initial velocity to be zero

substituting the value we get

[tex]v^2-0=2\times 9.8\times 2.3[/tex]  

[tex]v=\sqrt{2\times 9.8\times 2.3}[/tex]  

[tex]v=6.71\ m/s[/tex]
