Physics help ??

Answer 1

the sum of the forces in the x direction is `24.1` Newtons.

Explanation:

The horizontal forces in this situation will be the force of friction (a negative force) and the horizontal component of the applied force.

By trigonometry we see that

`F_(A"horizontal") = 28cos(12˚) = 27.4 N`

You should subtract the force of friction from this. Therefore, the net horizontal force will be `27.4 N - 3.3 N = 24.1 N`.

If you knew the mass of the tourist you could find the acceleration from this by dividing the net force by the mass (since `f_"net" = ma)`

Hopefully this helps!
