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>
£ 54</h2>
Step-by-step explanation:
Given,
Discount percent = 10%
Marked price ( MP ) = £ 60
Selling price ( SP ) = ?
Now, finding the discount amount:
Discount amount = discount percent of MP
= 10% of 60
= £ 6
Selling price = Marked price - Discount amount
=£ 60 - £ 6
= £ 54
hope this helps...
Good luck on your assignment..
Answer:
it is 0.21.
Step-by-step explanation:
21% means 21 out of 100. A fraction is the top divided by the bottom. 21 divided by 100 is 0.21 and that's 21 hundredths so as a fraction it is 21/100 It cant be simplified further. Hope that explains it better than the other answer.
