Must answer ALL parts for upvote **Physics Problem: Children's Wagon Acceleration**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 87.0 N, friction is 9.00 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.)- [ ] the children outside the wagon- [ ] the wagon- [ ] the child in the wagon**(b)** Draw a free-body diagram, including all forces acting on the system.**Free-Body Diagram Explanation:**Four diagrams are presented that need to be analyzed:1. **Diagram 1:** - Forces are depicted with the following labels: - \( \vec{N} \) (Normal force) upwards. - \( \vec{T} \) (Tangential force) leftwards. - \( \vec{F_2} \) (Force by second child) rightwards. - \( \vec{F_1} \) (Force by first child) leftwards. - \( \vec{W} \) (Weight force) downwards. 2. **Diagram 2:** - Similar to Diagram 1 with arrows in the same direction. 3. **Diagram 3:** - Similar arrangement to Diagram 1 and 2, featuring consistent force arrows. 4. **Diagram 4:** - Similar directional layout, arrows showing interaction of forces.**(c)** Calculate the acceleration in \( \text{m/s}^2 \). (Enter the magnitude.)\[ \boxed{ \text{ }} \text{m/s}^2 \]**(d)** What would the acceleration be (in \( \text{m/s}^2 \)) if friction were 15.0 N? (Enter the magnitude.)\[ \boxed{ \text{ }} \text{m/s}^2 \]---These components are integral for solving problems involving Newtonian mechanics, specifically emphasizing the calculation of acceleration due to applied forces and resistance such as friction.
