Two dogs pull on a toy. One pulls with a force of 10 N, the other with a force of 15 N. In what relative directions can the dogs act to give the toy the smallest acceleration?

They must act one opposite of the other, so the resultant hits the minimum of 5 N. When they go in the same direction you get the maximum of 15 N.

For the smallest acceleration of the toy, Dog 1 should pull in one direction while Dog 2 pulls directly opposite. This results in the forces opposing each other, minimizing the net force acting on the toy. Opposite directions create a smaller resultant force and lower acceleration accordingly.
