1m/s${{^2}}$in the -x direction

Work Step by Step

There are two forces that act on the 5kg object, one that is 30N in the +x direction and one that is 35N in the -x direction. This means that net force is +30-35=-5N, or 5N in the -x direction. Using F=ma, we can see that Acceleration=${\frac{Force}{Mass}}$ = ${\frac{-5 N}{5kg}}$ =-1m/s${{^2}}$ = 1 m/s${^2}$ in the -x direction
