Answer:

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!
