Answer
Explanation:
Step1: Recall acceleration formula
Acceleration $a=\frac{\Delta v}{\Delta t}$, where $\Delta v$ is change in velocity and $\Delta t$ is change in time.
Step2: Calculate acceleration between 0 - 0.5 s
$\Delta v = 5 - 0=5$ m/s, $\Delta t=0.5 - 0 = 0.5$ s. So $a_1=\frac{5}{0.5}=10$ m/s².
Step3: Calculate acceleration between 0.5 - 1 s
$\Delta v = 10 - 5 = 5$ m/s, $\Delta t=1 - 0.5 = 0.5$ s. So $a_2=\frac{5}{0.5}=10$ m/s².
Step4: Calculate acceleration between 1 - 1.5 s
$\Delta v = 15 - 10 = 5$ m/s, $\Delta t=1.5 - 1 = 0.5$ s. So $a_3=\frac{5}{0.5}=10$ m/s².
Answer:
A. The acceleration is a constant.
