graphing motion: mastery test\nin this graph, what is the displacement of the particle in the last two seconds?\na. 0.2 meters\nb. 2 meters\nc. 4 meters\nd. 6 meters
Answer
Explanation:
Step1: Recall displacement - velocity - time relation
Displacement $d = v\times t$ for constant - velocity motion.
Step2: Identify velocity and time values
From the graph, the velocity $v = 1.0$ m/s and the time interval $\Delta t=2$ s (last two seconds from $t = 4$ s to $t = 6$ s).
Step3: Calculate displacement
$d=v\times\Delta t=1.0\times2 = 2$ m
Answer:
B. 2 meters
