alleryStart learning →Layla jogs with an average velocity of 2.4 m/s east. What is her displacement after 46 seconds?
A19 m east
B48 m east
C110 m east
D220 m east
Answer & Solution
Correct answer: C. 110 m east
1. Displacement equals average velocity multiplied by time.
2. delta d = (2.4 m/s)(46 s) = 110.4 m east.
3. Rounded to two significant figures this is 110 m east.
