Question

Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force of 75.0 N, the second a force of 90.0 N, friction is 12.0 N, and the mass of the third child plus wagon is 23.0 kg.

What is the system of interest if the acceleration of the child in the wagon is to be calculated?
Draw a free-body diagram, including all forces acting on the system.
Calculate the acceleration.
What would the acceleration be if friction were 15.0 N?
