Could someone make an example grid, so I know what to follow?

We were doing sample problems similar to this in class, and he said all we had to do was this: http://img232.imageshack.us/img232/7516/78692884fy5.jpg for these kind of problems. I will attempt to make a new grid...

Please explain that.. I am clueless on this matter

Homework Statement a boat is a drift in a stream that flows at 3 mph 40* north of east. A wind blowing at 11 mph from a direction 50*NW also moves the boat. What will be the net direction and speed of the boat? Homework Equations Vwa = 3mph 40* NE Vwi = 11mph 50* NW The Attempt at...

Should I Just write, not enough info. on my paper? He didnt tell us to search for the radius.

The other property would be volume, but I don't know how to get it with the given info..

Yes, sorry about not including the conversions in my OP.. http://img293.imageshack.us/img293/4198/92845158ma2.png

Thank you, but all I got is{5.97 e ^3}KGfor a number... They are asking for the density of the Earth in pounds per cubed foot.

The mass of the Earth is 5.97 e 24 KG. If density = mass/volume, what would be the density of the Earth in pounds/ft(3) 5.97 e24 KG X 2.2 lbs x 1ft(3)/62.4lbs = 2.1 e23 ft(3)... I don't know what to do after this, or am I even on the right track?
