Answer:
The final velocity of your motion is 19.5 m/s.
Explanation:
Given;
initial velocity of your motion, u = -3.0 m/s
acceleration of your motion, a = 2.5 m/s²
time of your motion, t = 9.0 s
The final velocity of your motion is calculated as follows;
v = u + at
where;
v is the final velocity
substitute the given values and solve for v
v = -3.0 + (2.5 x 9)
v = -3.0 + 22.5
v = 19.5 m/s
Therefore, the final velocity of your motion is 19.5 m/s.

Explanation:
A chemical change results from a chemical reaction, while a physical change is when matter changes forms but not chemical identity. Examples of chemical changes are burning, cooking, rusting, and rotting. Examples of physical changes are boiling, melting, freezing, and shredding. Often, physical changes can be undone, if energy is input.
Average oceanic crust thickness = (3+6)/2 = 4.5 mi
Average continental crust thickness = (20+30)/2 = 25 mi
Average Earth's crust thickness = (4.5+25)/2 = 14.75 mi
