Question

Bob can row 5 mph In still water. He rows directly across a river flowing at 6 mph. Using vectors, find his resultant

Answer 1

Answer:

7.81mph

Step-by-step explanation:

Using the pythagoras theorem;

resultant r is expressed as;

r² = 5² + 6²

r² = 25 + 36

r² = 61

r =√61

r = 7.81mph

Hence the resultant speed is 7.81mph
