Answer :
We have that the value of x_0 is
[tex]x_0=7m[/tex]
From the question we are told that
height of 5 m
initial velocity of 7 m/s
[tex]x_0=7\\\\x_0=−9.8 m/s\\\\x_0=5[/tex]
From the correct diagram
Generally the equation for the Time is mathematically given as
[tex]t=\sqrt{\frac{2h}{g}}\\\\x_0=7*\sqrt{\frac{2xh5}{9.8}}[/tex]
x_0=7m
