In this given problem, to solve for the acceleration we have to
assume that the acceleration is constant. This assumption helps us understand
that the velocity of Dave follows a linear increase and hence we can use the
formula below for calculating the acceleration:
a= (Vf – Vi) / t
where
Vf = final velocity = 7.0 m / s
Vi = intial velocity = 3.0 m / s
t = time elapsed = 10 s – 5 s = 5 s
Substituting the known values into the equation:
a = (7.0 m / s – 3.0 m / s) / 5 s
a = 0.8 m / s^2
Answer:
<span>D. 0.8 m/s2</span>
It's true, I just got that question right on my odysseyware.

Answer:
sharing a password with a friend
Explanation:
this is what they said was right when we did this unit in school
1. True- because scientific theory means that <span>idea supported through research that attempts to explain existing observations or predict new ones.</span>2. False- because a cross-sectional means that its a study that is about different groups.
3. B-<span>An extraneous variable clarifies the relationship between the independent and dependent variables.</span>
