Question

A squirrel falls from this tree after being shocked by the falling apples. If the

squirrel was 3.5 meters above the ground, how long until the squirrel hits the
ground?

Answer 1

0.85m

Step-by-step explanation:

Given parameters:

Height of fall = 3.5m

Unknown:

Duration of fall = ?

Solution:

To solve this problem, we apply the right motion equation.

Since we know the height, we can use the equation below;

S = ut +
`(1)/(2) gt^(2)`

S is the height

u is the initial velocity = 0m/s

t is the time

g is the acceleration due to gravity

3.5 = 0 +
`(1)/(2)` x 9.8 x t²

3.5 = 4.9t²

t² =
`(3.5)/(4.9)`

t² = 0.71

t = √0.71 = 0.85m
