Answer:
(2,1)
Step-by-step explanation:
X=2 and y=1
UPWARD JOURNEY
(g is -ive)
u= 80.5m/s
Height reached= u^2/2g= 324m
Height of the ball at topmost point of journey= 414m
DOWNWARD JOURNEY
(g is +ive)
u=0
We need to find the velocity at 89m from ground, which is equivalent to finding velocity at 325 m from the topmost point in downward direction.
v= √2gh= √2*10*325= 80.6= 81 m/sec(Answer)

Answer:
<h3>The value of the second number is <em><u>24</u></em><em><u> </u></em>and the first no <em><u>12</u></em><em><u>.</u></em></h3>
Step-by-step explanation:
<h3> Greetings !</h3>
From, the given word explanation try to create your own equation like
- x + y = 36... (1) let the two numbers be x and y respectively.
- 2x = y ....(2) let x be the first no and it's twice that of the second number.
From, equation (1) solve for x
- x + y = 36
- x = 36-y... (3)
Substitute, equation (3) to equation (2).
- 2(36-y) =y
- 72 - 2y =y
- 72 = y + 2y.... solve for y
- 72 = 3y.... divide both sides by 3
- 72/3 = y..
- <em><u>y=24</u></em><em><u> </u></em><em><u>.</u></em>..simplified
