Answer:
[tex]-5.0 m/s^2[/tex]
Explanation:
Missing question:
What is the object's acceleration?
Solution:
The acceleration of an object is given by
[tex]a=\frac{v-u}{t}[/tex]
where
v is the final velocity
u is the initial velocity
t is the time taken for the change in velocity
For the object in this problem,
u = +25 m/s
v = +15 m/s
t = 2.0 s
Substituting,
[tex]a=\frac{15-25}{2}=-5.0 m/s^2[/tex]
And the acceleration is negative because its direction is opposite to that of the velocity.
