<span>Science is always defined as the body of knowledge and linked to something
related to the physical world, phenomena and lives of everything that exist on
Earth. Science is categorized in various ways. Pure, practical or theoretical, is the largest
distinction of science or whether
science is applied. Generally, pure
science is subdivided into Physical sciences, Earth sciences, and Life
sciences. Physical sciences deal with
energy and matter, Earth sciences explain Earth’s phenomena, to the solar
system where it belongs and its atmosphere. And finally, life sciences describe
internal processes of living organisms, its relationship to each other and to
its environment.</span>

Explanation:
I think the third one coz it's so good
Answer:
KE_2 = 3.48J
Explanation:
Conservation of Energy
E_1 = E_2
PE_1+KE_1 = PE_2+KE_2
m*g*h+(1/2)m*v² = m*g*h+(1/2)m*v²
(0.0780kg)*(9.81m/s²)*(5.36m)+(.5)*(0.0780kg)*(4.84m/s)² = (0.0780kg)*(9.81m/s²)*(2m)+KE_2
4.10J+0.914J = 1.53J + KE_2
5.01J = 1.53J + KE_2
KE_2 = 3.48J
The forces cancel out each other because they are equal and opposite. Therefore the net force is 0 and there will be no acceleration
