Question

An aeroplane is heading north at a speed of 300km/h . If wind begins blowing at a speed of 50km/h from the west , calculate the magnitude of the velocity of the aeroplane relative to ground?

Answer 1

sqrt (300^2 + 50^2)

Answer 2

R^2= y^2+ x^2
R^2=300^2+50^2
R^2=90,000+2,500
R^2=√92,500
R=304.14km/h

Answer 3

Thanks so much
