The child pushed the baby walker 2.8 m across a horizontal floor. The work done by the child was 35 J.

Calculate the horizontal force the child applied to the baby walker.

From the previous question, the equation is W = Fs. We need to calculate the force, F. So we must rearrange the equation: F = W / s The question gives the values: Work done (W) = 35 J Distance (s) = 2.8 m Substitute these values into the rearranged equation: F = 35 / 2.8 F = 12.5 N The unit for force is Newtons (N).
