Question

An apple falls straight down from a tree and hits the ground in approximately 0.75 seconds. Based on this information, which is most likely the placement of the apple in the tree?

Answer 1

Answer:

y = 2.76 [m]

Explanation:

We can find the distance of the fall of the apple using the following kinematic equation, we have to emphasize that this is a typical problem of free fall, so the initial speed is zero, then we give the initial data.

t = time = 0,75[s]

g = gravity = 9.81[m/s^2]

v0 = 0

$y = v_{0}*t+0.5*g*t^{2}\\ y=0.5*(9.81)*(0.75)^{2}\\y= 2.76[m]$
