Time while going up = time while going down.
One-way time = 0.47 / 2 = 0.235 s
While going up,
s = ut + 1/2 at²; where u is the initial velocity upwards and a is the acceleration due to gravity downwards.
2.14 = u(0.235) + 1/2 x -9.81 x (0.235)²
u = 10.2 m/s
Max height attained can be obtained by:
2as = v² - u²; where v is 0
s = -(10.2)² / -9.81 x 2
s = 5.30 m
The height above the window is:
5.30 - 2.14
= 3.16 m
Answer:
<h2>5.3cm</h2>
Step-by-step explanation:
Step one:
given data
First tree
the tree is 8cm tall
and 30cm from the vanishing point
Third tree
let the tree be x cm tall
and 20cm from the vanishing point
Step two:
<em>if 8cm tree will be 30cm at the vanishing point</em>
<em>then x cm tree will be 20cm at the vanishing point</em>
cross multiply we have
x= (20*8)/30
x=160/30
x=5.3cm
<u>The third tree is 5.3cm tall</u>
