Suppose two children push horizontally, but in exactly opposite directions, on a third child in a wagon. The first child exerts a force of 72.0 N, the second a force of 95.0 N, friction is 18.0 N, and the mass of the third child plus wagon is 23.0 kg. (a) What is the system of interest if the acceleration of the child in the wagon is to be calculated? (Select all that apply.) O the children outside the wagon O the child in the wagon O the wagon (b) Draw a free-body diagram, including all forces acting on the system. W

I Review A coin is lying at the bottom of a pool of water that is 7.3 feet deep. Part A Viewed from directly above the coin, how far below the surface of the water does the coin appear to be? (The coin is assumed to be small in diameter; therefore, we can use the small-angle approximations sine = tan0 = 0.)
