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?
A.
17.0m
B.
18.0m
C.
22.5m
D.
30.0m
Correct answer is B
distance = area under the graph.
= \(\frac{1}{2}\times 1 \times 4 ) + \frac{1}{2} \times (4+6)\times 1) + (6 \times 1.5) + (\frac{1}{2}\times(2 + 6)\times 0.5)\)
