Problem 2.42 Enhanced with Feedback ) 12 of 13 Constants Peridc Table Part A Lolliguncula brevis squid use a form of jet propulsion to swim they eject water out of jets that can point in different directions, allowing them to change direction quickly. When swimming at a speed of 0.15 m/s or greater, they can accelerate at 1.2 m/s2 Determine the time interval needed for a squid to increase its speed from 0.15 m/s to 0.35 m/s Express your answer with the appropriate units. t 0.167 s Correct Significant Figures Feedback: Your answer 0.16 s was either rounded differently or used a different number of significant figures than required for this part. Part B Determine the distance the squid has traveled while accelerating Express your answer with the appropriate units. d- 0.039 Submit Incorrect, Try Again; 5 attempts remaining

Explanation / Answer

Part B

We have to use, third equation of.motion here.

v 2-u 2=2as

0.352-0.152=2*1.2*s

s=0.04167 m
