It's Friday night and Hector has been assigned the noble task of baby-sitting Jacob, his 2-year old brother. He puts a crash helmet on Jacob, places him in a red wagon and takes him on a stroll through the neighborhood. As Hector starts across the street, he exerts a 58.2 N forward force on the wagon. There
is a 21.3 N resistance force against the wagon (due to friction) and the wagon and Jacob have a combined weight of 317 N. Determine the magnitude of
the net force, the mass of the wagon (with Jacob), and the horizontal acceleration of the wagon. (Note: acceleration due to gravity = 9.81 m/s/s)
