Asked by peter


An object with a mass of 3.09x10^0 kg is subjected to a force of 8.8505x10^2 N directed at an angle of 1.6968x10^2 degrees from the x axis. A second force of 2.98725x10^3 N acting in the negative Y directions is also applied to the object. To two significant figures what is the net force acting in the Y direction (remember to include weight!)?
Note: Your answer is assumed to be reduced to the highest power possible.
Your Answer: x10

You have not said what direction is vertical. That would be the direction in which the weight force (30.28N) must be added. Once you know that, this is a routine vector addition problem with three vectors, and you only have to add components in the y direction.

I am left wondering why they are quoting forces to five significant figures and only asking for accuracy of two figures in the answer.
