**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?

Two thieves want to steal a 1mx1mx1m Lazada Mystery Box worth of 1million pesos that is placed on a warehouse with a cemented floor. When they successfully break into the warehouse using a bobby pin they realize that they both cannot carry the 400 lb package, so they decided to push it out of the warehouse. If the untouched package and the cemented floor has a coefficient of friction of 0.400, what is the maximum amount of force they first need to exert in order to make the package move when they will: A) push the package with their hands 90 degree with the vertical wall of the box. B) push the package with their hands in 120 degree with the vertical wall of the package. C) When they decided to pull the box instead and their hands are in 120 degree with the top edge of the box.

An SUV containing 5 passengers has a mass of 3500 kg. It has a driving force of 2500 N directed west on a perfectly horizontal road. The surface of the road exerts a resistive force of 500 N due east. At the same time, a strong wind is blowing a force of 500 N due east in the opposite direction of the car's drive force. Does the car have any acceleration? If yes, then what is the magnitude and direction of the car's acceleration?
A 60 kg block slides along the top of a 100 kg block. The lighter block has an acceleration of 3.8 m/s2 when a horizontal force F= 390 N is applied. Assuming there is no friction between the bottom 100 kg block and the horizontal frictionless surface but there is friction between the blocks. Find the acceleration of the 100 kg block during the time the 60 kg block remains in contact.
