Question

multiple choice 0.5 points
what is the total distance traveled from a to f?
table 2.1 position of
the car at various times
position t (s) x (m)
a 0 30
b 10 52
c 20 38
d 30 0
e 40 -37
f 50 -53
83 m
127 m
99 m
53 m

Explanation:

Step1: Calculate A to B distance

$|52 - 30| = 22$ m

Step2: Calculate B to C distance

$|38 - 52| = 14$ m

Step3: Calculate C to D distance

$|0 - 38| = 38$ m

Step4: Calculate D to E distance

$|-37 - 0| = 37$ m

Step5: Calculate E to F distance

$|-53 - (-37)| = 16$ m

Step6: Sum all segment distances

$22 + 14 + 38 + 37 + 16 = 127$ m

Answer:

B. 127 m
