A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk....

A husband and wife take turns pulling their child in a wagon along a horizontal sidewalk. Each exerts a constant force and pulls the wagon through the same displacement. They do the same amount of work, but the husband's pulling force is directed 58° above the horizontal, and the wife's pulling force is directed 38° above the horizontal. The husband pulls with a force whose magnitude is 71 N. What is the magnitude of the pulling force exerted by his...
