1) C. velocity
Acceleration is defined as the rate of change of velocity per unit time. In formulas:
where
is the change in velocity
is the time interval
Therefore, the correct answer is C. velocity.
2) A. 9.8m/s/s
Earth's gravity is a force, so it produces an acceleration on every object with mass located on the Earth's surface. This acceleration can be calculated, as it is given by the formula
where
is the gravitational constant
is the Earth's mass
is the Earth's radius
By substituting these numbers into the formula, one can find that the acceleration due to Earth's gravity is 
.
The answer is A.) igneous rocks
Answer:
The answer is
<h2>7,840,000 J</h2>
Explanation:
The kinetic energy KE of an object given it's mass and velocity can be found by using the formula
where
m is the mass
v is the velocity
From the question
m = 20000kg
v = 28 m/s
It's kinetic energy is
We have the final answer as
<h3>7,840,000 J</h3>
