Divide the distance traveled by the time it took:
(100 m) / (4.2 s) ≈ 23.8 m/s
The answer is B. A frame of reference that is accelerating.
C. Travels slower in solids because the particles are closer together.

Glaciers slow moving enormous masses knocking out great chunks of rock.
wind faster moving, more like sandpaper (sand storms in deserts ?)
Answer:
Kinematics of the parabolic movement
To solve the problem we will apply the kinematic equations of linear motion, which are an essential part in the characterization of parabolic motion. In this case we require the definition of acceleration described mathematically as,
a
=
v
f
−
v
i
t
Here,
v
f
=
Final Velocity
v
i
=
Initial Velocity
t
=
Time

According to the information provided we have to
{eq}\text{Initial Velocity} = v_i = 4.0\text{ m/s}\\ \text{Initial Velocity} = v_f = 0.80\text{
