(1)
Where:
is the ball maximum height
is the time
is the initial height
With this information the equation is rewritten as:
(2)
Now, we have to find , and this will be posible with the following formula:
(3)
Where:
is the final velocity of the ball at the point where its height is the maximum
is the acceleration due gravity
Isolating :
(4)
(5)
(6)
Substituting (6) in (2):
(7)
Finally:
Answer:
Area of river = 3 × 40
= 120
amount of water that falls into the sea ⇒
= Area × rate
= 120 × 2
= 120×
= 2 × 2000
= 4000
∴4000 of water falls into the sea permin.
