Answer:
3.63 meter/sec²
Step-by-step explanation:
When a rock fall from a height h with initial velocity u and the rock reaches the surface in t seconds the expression that represents this is
h = 4t + gt²
Where g is the acceleration due to gravity
Here h = 0.72 meters
u = 0
t = 0.63 seconds
from the given formula
0.72 = 0 ×(0.63) + g(0.63)²
0.72 = g(0.63)²
g =
= 3.63 meter/sec²
