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 to the left, the second a force of 90.0 N to the right, the force of friction acts in the direction opposite to the motion of the cart and has a magnitude of 12.0 N. The mass of the third child plus wagon is 23.0 kg. a. Draw a diagram showing all forces acting on the third child. b. Calculate the child’s acceleration. c. What would the acceleration be if the magnitude of the force of friction were 15.0 N?
