Question

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

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
