15 refer to the graph to find the acceleration of the moving object between 0 seconds and 5 seconds. a 6 m/s/s b 30 m/s/s c -6 m/s/s d 0 m/s/s
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: Determine initial and final velocities
At $t = 0\ s$, $v_0=0\ m/s$. At $t = 5\ s$, $v = 30\ m/s$. So $\Delta v=v - v_0=30 - 0=30\ m/s$ and $\Delta t=5 - 0 = 5\ s$.
Step3: Calculate acceleration
$a=\frac{\Delta v}{\Delta t}=\frac{30}{5}=6\ m/s^2$
Answer:
A. 6 m/s/s
