Answer:
Hello your question is incomplete below is the missing piece
What is the magnitude of the boat’s resultant velocity? Round your answer to the nearest whole number.
answer : 25.73 m/s
Explanation:
Given
V1 = 15 miles/hour = 6.71 m/s [ 45° EN ]
V2 = 18 m/s [ 5° NE ]
Calculate the resultant velocity
Vr = 6.71 m/s[45°] + 18m/s[5°].
Vr = ( 6.71 *Cos45° + 6.71 *sin45°) + ( 18 *Cos5° + 18*sin5° )
Vr = ( 4.74 + 4.74 i )+ ( 17.93 + 1.57i) = 22.67 + 12.18i.
Therefore the magnitude
= [tex]\sqrt{22.67^2 + 12.18^2}[/tex] = 25.73 m/s
