A motorboat heads due south at 16 meters per second across a river that flows due east at 9 meters per second. What is the resultant velocity of the motorboat? (Round to nearest tenths)

Respuesta :

ok

[tex]\begin{gathered} \text{resultant = }\sqrt[]{16^2+9^2} \\ \text{resultant = }\sqrt[]{256\text{ + 81}} \\ \text{resultant = }\sqrt[]{337} \\ \text{resultant = 18.4 m/s} \end{gathered}[/tex]

result = 18.4 m/s
