Please show the solution for this story problem: A bird sitting 16 feet above the ground in an apple tree dislodges an apple.
After how many seconds does the apple land on the ground? (Assume no branches interfere with its fall.)
I would greatly appreciate your help on this problem.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Let me re-formulate it in Math or Physics terms.
After how many seconds does the apple land on the ground, if it falls from the height 16 ft ?
The distance the free falling body falls in t seconds is h = ,
where g = 32 ft/s^2 is the gree fall acceleration (approximately).
So, what you need is to solve this equation
16 =
for t. Multiply both sides by , and you will get
= 1, which gives you the answer t = 1 second.
Answer. In 1 second.
