I know this is basic stuff, but if anyone would be willing to help... :)
At a certain time, a car is 150 meters due west of your house. If it is traveling with a constant velocity of 30m/s 30 degrees south of east, what are the ,magnitude and the direction of its position relative to your house 5 seconds later?
30m/s(5s)=150m
150cos30= roughly 130 m
150sin30=75m
150m-130m=20m
mag=sqrt((75^2)+(20^2))=77.6m
tan inverse(75/20)= 75 degrees
So, the car is 77.6 meters away from the house at an angle of 75 degrees, south of west.
Does that seem correct?
Thanks
