Explanation:
At year six more land became avaliable this is the only way that the population could grow so fast and it is correct on edg.
If a constant force is applied on a body, the body moves with constant acceleration.
Technically it is referred to as <em>star brightness</em> but yes you have the general idea.
This is an example of slowing down because you encountered heavy traffic or just got tired.
Also, the numbers show acceleration.
Answer:
17.86 m
Explanation:
The first step is to find the velocity of the swimmer.
Velocity, v = s/t
Velocity, v = 5 / 0.27
Velocity, v = 18.52 m/s
Then, we find the height
h = ½gt²
h = ½ * 9.8 * 0.27²
h = 4.9 * 0.0729
h = 0.36 m
Next, we apply the law of conservation of energy
mgH = mgh + ½ mv²
9.8Hm = m(9.8 * 0.36 + 0.5 * 18.52²)
9.8H = 3.528 + 171.4952
9.8H = 175.02
H = 175.02 / 9.8
H = 17.86 m
Therefore, the needed height is 17.86 m
