Homework Statement
Bob walks 160 m south, then jogs 630 m southwest, then walks 160 m in a direction 32degrees east of north.
a) Use either trigonometry or components to find the displacement that will return Bob to his starting point by the most direct route. Give your answer as a distance.
b)Find the direction of the displacement that will return Bob to his starting point by the most direct route.
Homework Equations
Not sure what to use.
The Attempt at a Solution
I'm not even sure where to begin, even some hints to tell me how to start would be very useful!
a)
60 + 630(cos45+sin45) + 160(cos32,sin32)
60 + 630(0.71 + 0.71) + 160(0.848 + 0.5299)
60 + 447.3 + 447.3 + 135.688 + 84.787
642.98 + 533.087
642.98^2 + 533.087^2
413423.28 + 284181.83
697605
take root = 835.22
