Answer:
Explanation:
Find the final velocity at which it struck the ground by using the kinetic energy formula.
[tex]KE=\frac{1}{2} mv^2[/tex]
[tex]2000=\frac{1}{2} (15)v^2\\v=16.33[/tex]
Now use kinematics to solve for the vertical displacement. We were given the initial velocity and acceleration can be assumed to be 9.8
[tex]V^2=V^2_i+2a(y_f-y_i)\\16.33^2=0^2+2(9.8)(y_f-y_i)[/tex]
Δy = 13.6 meters
