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)

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)
