lf an object's velocity changes from 25 meters per second to 15 meters per second in 2.0 seconds, the magnitude of the object's acceleration is​

Respuesta :

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.
