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.)
Thank you.
when is
16t^2 = 16 ??
same question about 4 years ago?

To find the time it takes for the apple to land on the ground, we can use the kinematic equation for free fall. The equation is:
h = 0.5 * g * t^2
Where:
h is the height (in this case, 16 feet)
g is the acceleration due to gravity (approximately 32.2 feet per second squared)
t is the time we want to find
Rearranging the equation to solve for t, we have:
t = sqrt(2*h / g)
Plugging in the given values:
t = sqrt(2*16 / 32.2)
t = sqrt(0.9926)
t ≈ 0.996 seconds
Therefore, it takes approximately 0.996 seconds for the apple to land on the ground.
