Question

Magnitude =57.98km/h , need direction please!

Answer 1

Answer #1

V_initial=-77i

V_final=33cos45i+33sin45j=23.33i+23.33j

V=-77i+23.33i+23.33j=-53.67i +23.33j

magnitude

|V|=sqrt[(-53.67)²+23.33²]=58.5 km/h

direction

o=tan^-1(23.33/-53.67)=-23.5^o

23.5^o north of west

A glider aircraft initially traveling due west at 84.0 km/h encounters a sudden gust of wind at 34.5 km/h directed toward the northeast. What are the speed and direction of the glider relative to the ground during the wind gust?
