You can
put this solution on YOUR website!I'll convert the velocity vectors to distance vectors. Then
I'll find the points on the x-y plane where the end up and use the distance formula
" One travels in the direction 60 degrees east of north."
That's the same as 30 degrees N of E. In a half-hour this car
would have gone 60 km/hr x 1/2 hr = 30 km
The component along the y-direction is
The component along the x-direction is
--------------------
" The other travels in the direction 45 degrees east of south."
That's the same as 45 degrees south of east
This car also would have gone 60 km/hr x 1/2 hr = 30 km
The component along the y-direction is
The component along the x-direction is
---------------------
Now I have 2 points
(
,
)
and
(
,
)
Now I use the distance formula
km
