Answer:
c 8.80 s
Explanation:
Given parameters:
Height of Empire State Building = 380m
Unknown:
Time taken for King Kong to fall = ?
Solution:
To solve this problem, we use one of the kinematics equation.
The appropriate one is given below;
H = ut + [tex]\frac{1}{2}[/tex] g t²
H is the height
t is the time taken
g is the acceleration due to gravity
380 = (0 x t) + ( [tex]\frac{1}{2}[/tex] x 9.8 x t²)
380 = 4.9t²
t² = 77.55
t = 8.8s
