what is the difference between vector displacement and a resultant? :confused:
my problem is this:
A plane travels 25 km at an angle of 35 deg. to the ground, then changes direction and travels 515 km at an angle of 22 deg. to the ground. Find the magnitude and direction of the planes total displacement.
whats the displacement? the addition of the two vectors?
Since a vector quantity has direction, your resultant displacement is as follows.
In a right angle triangle, the displacement is the longest side, using pythagoras' theorem. Then, you can find the angle at which it's travelling using tan (Opp/Adj).
I hope that helps.
k thanks...the books defenition is sketchy, thanks for clearing it up :cool:
I just started a two year A-level course on mechanics, and a physics A-level module on vectors and stuff, and BOY am I getting fed up with resolving fricking vector diagrams for 3:20 every day...
Chuckle - we've all been there :p
