mohon bantuannya buat tgs fisika ini

c. maaf klo salah ya...

(*) first, let's us assume that the initial velocity of the object is v₀ = 0 m/s.

(**) when the object is the halfway to the ground (at height h/2), its speed is

v₁  = √gh

(***) its final speed before hitting the ground is

v₂ = √2gh

thus v₁/v₂ = 1/√2
