Logan pushes a box with a 400n of force with a direction angle of 30 degrees, while Andrew pushes the same box with a force of 250N with a direction angle of 290 degrees.what is the magnitude of the restaurant vector (force) on the box? Round your answer to the nearest tenth.

We will have the following:

We will determine the magnitude of the resulting force as follows:

We find the sum of forces on the x and y-axis and then we calculate the resulting force, that is:


\sum Fx=400cos(30)-250cos(70)\approx250.91
\sum F_y=400sin(30)-250sin(70)\approx-34.92

Now, we find the resulting force:


F_r=√((250.91)^2+(-34.92)^2)\Rightarrow F_r\approx253.3

So, the magnitude of the resulting force is approximately 253.3 N.
