Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force F, of 61 N, the second a force FR of 99 N, friction f is 10 N, and the mass of the third child plus wagon is 25 kg. Help: Consider the direction of the forces. The forces applied by the two children outside of the wagon are stated to be in opposition to one another. What about friction? With respect to the direction of motion, how does it act? Will its effect be additive or subtractive? (a) Calculate the acceleration. a= the wh m/s²
