What is the speed of a free falling object released from rest from a height h = 100m from the ground after 1.8 s of free fall? Neglect the effect of air resistance, and use g = 10 m/s2. 16 m/s O 22 m/s 24 m/s O 18 m/s 14 m/s​

Respuesta :

Answer:

18 [m/s].

Explanation:

1) formula:

[tex]g=\frac{V-V_o}{t}, \ where \ g-acceleration, \ V-\ final \ speed, \ V_o-initial \ speed, \ t-elapsed \ time.[/tex]

2) according to the formula above, the final speed is:

V=g*t; V=10*1.8=18 [m/s].
