Answer:
-5 m/s^2
Explanation:
[tex]acceleration = \frac{change \: in \: velocity}{time} \\ \\ = \frac{15 - 25}{2} \\ \\ = \frac{ - 10}{2} \\ \\ = - 5 \: m {s}^{ - 2} \\ \\ negative \: sign \: represents \: that \: \\ object \: is \: slowing \: down.[/tex]
Explanation:
Acceleration is the change in velocity over time.
a = Δv / Δt
a = (15 m/s − 25 m/s) / 2.0 s
a = -5.0 m/s²
The magnitude of the acceleration is 5.0 m/s².
