Answer:
[tex]\boxed {\boxed {\sf a= 1.5 \ m/s^2}}[/tex]
Explanation:
Acceleration is the change in velocity over time, so it is calculated using the following formula.
[tex]a= \frac{v_f-v_i}{t}[/tex]
The object is initially moving at 10.5 meters per second. After 2 seconds, it is moving at 13.5 meters per second.
- [tex]v_i[/tex]= 10.5 m/s
- [tex]v_f[/tex]=13.5 m/s
- t= 2 s
Substitute the values into the formula.
[tex]a= \frac{13.5 \ m/s - 10.5 \ m/s}{2 \ s}[/tex]
Solve the numerator.
[tex]a= \frac{3 \ m/s}{2 \ s}[/tex]
Divide.
[tex]a=1.5 \ m/s/s \\a= 1.5 \ m/s^2[/tex]
The acceleration of the object is 1.5 meters per second squared.
