Frictional Force


<div class="wp-block-create-block-problemblock">Hercules and Carlos horizontally push in the same direction on a 1200 kg crate.  Hercules pushes with a force of 500 N and Carlos pushes with a force of 300 N.  If a frictional force provides 200 N of resistance, what is the acceleration of the crate?<ul><li>1.3 m/s##^2##</li><li>1.0 m/s##^2##</li><li>0.87 m/s##^2## </li><li>0.75 m/s##^2## </li><li>0.5 m/s##^2##</li> </ul></div>
