Answer:
The required time is t = 8.8 [sg]
Explanation:
The solution to this problem can be achieved by means of the kinematics equations, where each of the variables y = 0, y0= 380 [m], g is the gravitational acceleration = 9.81[m/s^2], as the body falls in free fall the initial velocity is zero.
[tex]y=y_{0} + v_{0}*t-\frac{1}{2}*g*t^{2} \\\\where\\v_{0} =0\\y=0[m]\\[/tex]
[tex]0=-380+(0)*t-\frac{1}{2} *(9.81)*t^{2} \\\\t=\sqrt{\frac{380*2}{9.81} } \\t=8.8 [sg][/tex]
