I'm having a bit of trouble with a problem. I think i"m using the correct formula but want to be sure. Here is my problem.
Bob heads out into a lake at an angle of 47degrees with respect to the shore. If his boad is capable of speed of 2.7 m/s, how far from land will he be in 6 min and 52 s? Answer in units of m.
The formula I am tring to use is: Vx= vcos 47degrees
Vy= vsin47degrees
then one I've figured that I did
d=squareroot X^2=y^2 to get my time.
is this correct or do I need to be using one of the many other formulas to get my answer?
thanks
