Ierofanga [76]

Answer:

The kinetic energy at ground will be "238.2 J".

Explanation:

The given values are:

mass,

m = 3 kg

Initial height,

h = 3 m

Initial velocity,

v = 10 m/s

By using the conservation of energy at points A and B,

⇒ $E_A=E_B$

⇒ $mgh+\frac{1}{2}mv^2=k_B$

On substituting the values, we get

⇒ $3\times 9.8\times 3+\frac{1}{2}\times 3\times (10)^2=k_B$

⇒ $88.2+0.5\times 3\times 100=k_B$

⇒ $88.2+150=k_B$

⇒ $238.2 =k_B$

The loss of species of organisms is due to loss of their habitat.
If you went through a city and cut all the houses down to their
foundations, the people who lived in them would either die or
go somewhere else if they could.
