Suppose two children push herizontally, but in exactly opposite drections, on a third ch in a wagon The frst chd eerts force of 75.0N, the second a farce of 97.0 N, friction is 12.0 N. and the mass of the third child plus wagon is 28.0 g (a) What is the system of interest if tni acceleration of the chid in the wajon is to be calouated (Setect al that apply) Othe chidren outside the wagon Dthe wagon Othe chid in the wagon (b) Draw a free body diagram, including the weight and all other forces acting on the system. (Do this on paper. Your instructor may ak you to um n this diagram.) (c) Calculate the acceleration m/s (d) What would the acceleration be id friction is 22.0 N
