The velocity time graph above describes the motion of a particle between two points P and Q. What is the distance between P and Q?
17.0m
18.0m
22.5m
30.0m
설명
distance = area under the graph.
= \(\frac{1}{2}\times 1 \times 4 ) + \frac{1}{2} \times (4+6)\times 1) + (6 \times 1.5) + (\frac{1}{2}\times(2 + 6)\times 0.5)\) = 18m
