If the acceleration is constant, and the starting velocity is zero, the relationship between the acceleration of a falling body (a), the time it takes to fall (t), and instantaneous velocity when it hits the ground (v) is:
the general equation of acceleration is:
vf = vi + at
assuming the initial velocity (vi) is zero, the equation becomes:
vf = at
v = at
Answer:
Material that was produced by or was/is part of living organism
Explanation:
- organic is defined as the natural matter or compounds with a carbon base, and also refers to food and meat grown or raised without chemicals or pesticides.
-Natural plant matter is an example of something that would be described as organic.
D) they will all hit the ground at the same time. In the context that there is no air resistance and each object is in free fall, then they will have the same acceleration rate.
<span>As a crate slides down an inclined rough surface, its total mechanical energy decreases.
Since the surface of the incline is rough, friction is robbing mechanical energy from the crate all the way down, and blowing it away as heat into the surrounding air.</span>
