Question

an objects velocity vs time graph is plotted. what is the objects net displacement?
write your answer to 3 significant figures in standard decimal form.
____ m
velocity vs. time

Explanation:

Step1: Recall displacement formula for v-t graph

Displacement = Area under velocity-time graph. For a triangle, area = $\frac{1}{2} \times base \times height$.

Step2: Identify base and height

Base (time) = $15\ \text{s}$, Height (final velocity) = $10\ \text{m/s}$

Step3: Calculate the area

$\text{Displacement} = \frac{1}{2} \times 15 \times 10$
$\text{Displacement} = 75.0$

Answer:

75.0 m
