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>
