Starting from rest at $s=0,$ a boat travels in a straight line with the acceleration shown by the $a-s$ graph in $($Figure $1).$ Suppose that $a_1=6f\frac{t}{s^2}$ and $a_2=4f\frac{t}{s^2}.$

Option

$v=23\mathrm{.}5\frac{ft}{s}$

Previous Answers

Correct

Correct answer is shown. Your answer $23\mathrm{.}45\frac{ft}{s}$ was either rounded differently or used a different number of significant figures than required for t Here we learn how to find the velocity of a boat at the given position using the $a-s$ graph.

Part B

Determine the boat's speed when $s=100ft.$

Express your answer to three significant figures and include the appropriate units.
