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: Identify graph shape

The graph is a right triangle with base $t=15\ \text{s}$ and height $v=10\ \text{m/s}$.

Step2: Use displacement-area formula

Displacement equals area under velocity-time graph: $\text{Displacement} = \frac{1}{2} \times \text{base} \times \text{height}$
$\text{Displacement} = \frac{1}{2} \times 15 \times 10$

Step3: Calculate and round to 3 sig figs

$\text{Displacement} = 75.0$

Answer:

75.0 m
