Question

A child rows a rowboat north across a creek at 15 m/s. The creek flows east at 7
m/s.
What is the magnitude of the resultant velocity?

Answer 1

Answer:

16.55m/s

Explanation:

If a child rows a rowboat north across a creek at 15 m/s and creek flows east at 7

m/s. the magnitude of the resultant velocity is gotten using pythagoras theorem as shown

R² = 15²+7²

R² = 225+49

R² =274

R = √274

R = 16.55m/s

Hence the magnitude of the resultant velocity is 16.55m/s
