Answer:
-2.0 m/s^2
Step-by-step explanation:
Acceleration can be found by:
[tex] \displaystyle \large{ \frac{dv}{dt} = a }[/tex]
where a = acceleration.
or
[tex] \displaystyle \large{ \frac{v_2 - v_1}{t_2 - t_1} = a }[/tex]
Using two values or points.
t1 = 0 and v1 = 3
t2 = 1 and v2 = 1
Substitute in:
[tex] \displaystyle \large{ \frac{1-3}{1-0} = a } \\ \displaystyle \large{ \frac{ - 2}{ 1} = a } \\ \displaystyle \large{-2 = a }[/tex]
Therefore acceleration is -2.0 m/s^2
