how long does it take an acorn to hit the ground after dropping from the branch of a tree 12.5 m high?
Grace [21]
The right formula to use is: T^2= 2d/g
where T= time taken
d = 12.5m
g = is a constant and is equal to 9.8m/s
therefore, T^2 = 2*12.5/9.8 
Using the values above, the time taken for the acorn to reach the ground is 1.59 second
T = 1.59 S
