Answer to Question #1766 in Mechanics | Relativity for Net

Question #1766
A sail boat has initial coordinates (Xa ya) = (1000m,200m). Four minutes later it has a cooordinate (Xb Yb). Calculate&
(a) Components&
(b) The magnitude&
(c) the direction of the average velocity of the sailboat for the 4 mintime interval.
Expert's answer
The components of the speed can be found as
X: (Xb - Xa)/t; Y: (Yb - Ya)/t
The magnitude:
V = √((Xb-Xa)2 + (Yb - Ya)2) /t
The direction:
tan (θ) = (Yb-Ya)/(Xb- Xa)
