Answer 1

ANSWER:

58 m/s

STEP-BY-STEP EXPLANATION:

Given:

Initial velocity (u) = 13 m/s

The correct answer is 58 m/sDistance (d) = 400 m

Acceleration (a) = 4 m/s²

We apply the following formula to determine the final velocity:

[tex]\begin{gathered} v^2=u^2+2as \\ \\ \text{ We replacing:} \\ \\ v^2=13^2+2(4)(400) \\ \\ v^2=169+3200 \\ \\ v=\sqrt{3369} \\ \\ v=58.04\cong58\text{ m/s} \end{gathered}[/tex]

The correct answer is 58 m/s
