**Physics Problem: Forces and Acceleration****Part A**To give a 19-kg child a ride, two teenagers pull on a 4.2-kg sled with ropes, as shown in the figure. Both teenagers pull with a force of 72 N at an angle of 35° relative to the forward direction, which is the direction of motion. Additionally, the snow exerts a retarding force on the sled that points opposite to the direction of motion and has a magnitude of 68 N. Determine the magnitude of the acceleration of the sled + child (submit your answer with two significant figures).*Possibly useful equations:*- \( (F_{x})_{\text{net}} = ma_{x} \)- \( (F_{y})_{\text{net}} = ma_{y} \)- \( a = (a_{x}^{2} + a_{y}^{2})^{1/2} \)Your Answer: \[ 2.2 \, \text{m/s}^2 \] *Status: Correct*---**Part B**If one of the teenagers gets tired and only pulls with a force of 48 N while everything else remains the same, what is the new magnitude of the acceleration of the sled + child? (Submit your answer with two significant figures.)*Input box for answer submission.* **Explanation of Diagram:**There is an illustration showing the sled being pulled by two teenagers. Each of them initially exerts a force of 72 N at an angle of 35° away from the horizontal direction of motion. The resisting force of the snow is depicted opposite the direction of the movement, equal to 68 N. The problem involves calculating the resultant acceleration using the given forces.

When a parachute opens, the air exerts a large drag force on it. This upward force is initially greater than the weight of the sky diver and, thus, slows him down. Suppose the weight of the sky diver is 965 N and the drag force has a magnitude of 1016 N. The mass of the sky diver is 98.5 kg. Take upward to be the positive direction. What is his acceleration, including sign?
