Question

acceleration?
write your answer to 3 significant figures in standard decimal form.
_____ m/s²
velocity vs. time

Explanation:

Step1: Recall acceleration formula

Acceleration $a = \frac{\Delta v}{\Delta t} = \frac{v_f - v_i}{t_f - t_i}$

Step2: Identify graph values

Initial state: $v_i=0\ \text{m/s}$, $t_i=0\ \text{s}$; Final state: $v_f=9.5\ \text{m/s}$, $t_f=15\ \text{s}$

Step3: Calculate acceleration

$a = \frac{9.5 - 0}{15 - 0} = \frac{9.5}{15}$

Step4: Round to 3 significant figures

$\frac{9.5}{15} \approx 0.633$

Answer:

0.633 m/s²
