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.
