The speed of the mass when it hits the ground from the given height is [tex]\sqrt{2gh}[/tex].
The given parameters:
The final velocity of the ball when it hits the ground is calculated as follows;
[tex]v_f^2 = v_0_y^2 + 2gh\\\\[/tex]
where;
[tex]v_f^2 = 0 + 2gh\\\\v_f^2 = 2gh\\\\v_f = \sqrt{2gh}[/tex]
Thus, the speed of the mass when it hits the ground from the given height is [tex]\sqrt{2gh}[/tex].
