3. Imagine that a large professional wrestler is going to play tug-of-war with a little girl. They grabeach other's left hand and pull as hard as they can in purely horizontal directions. The result ofthe tug-of-war is that the wrestler remains stationary, but the little girl accelerates horizontallytowards the wrestler.Which person puts a larger force of pulling on the other and why?The forces would still be equal. Newton's Brd kw states when tobodies are interacting, they apply forces that are equal inmagnitude and nave opposite directions.Explain why the wrestler wins the tug of war. (A complete answer will include a free bodydiagram and a discussion with Newton's second law for each person.)7

Two people pull as hard as they can on horizontal ropes attached to a boat that has a mass of 200 kg. If they pull in the same direction, the boat has an acceleration of 1.52 m/s2 to the right. If they pull in opposite directions, the boat has an acceleration of 0.518 m/s2 to the left. What is the magnitude of the force each person exerts on the boat? Disregard any other horizontal forces on the boat.
What is the unbalanced force acting on a moving car with a constant velocity of 25 m/s (56 mi/h)?
Why does an ordinary rifle recoil (kick backward) when fired? The barrel of a recoilless rifle is open at both ends. Describe how Newton's third law applies when one is fired. Can you safely stand close behind one when it is fired?

Suppose you have a 120-kg wooden crate resting on a wood floor. (a) What maximum force can you exert horizontally on the crate without moving it? (b) If you continue to exert this force once the crate starts to slip, what will the magnitude of its acceleration then be?
While sliding a couch across a floor, Andrea and Jennifer exert forces FA and FJ on the couch. Andrea’s force is due north with a magnitude of 130.0 N and Jennifer’s force is 32 east of north with a magnitude of 180.0 N. (a) Find the net force in component form. (b) Find the magnitude and direction of the net force. (c) If Andrea and Jennifer’s housemates, David and Stephanie, disagree with the move and want to prevent its relocation, with what combined forceFDS should they push so that the couch does not move?
Why can we neglect forces such as those holding a body together when we apply Newton's second law of motion?
Suppose your friend is sitting on a sled and asks you to move her across a flat, horizontal field. You have a choice of (a) pushing her from behind by applying a force downward on her shoulders at 30 below the horizontal (Fig. 4.22a) or (b) attaching a rope to the front of the sled and pulling with a force at 30 above the horizontal (Fig. 4.22b). Which option would be easier and why?

A person doing a chin-up weighs 700 N, exclusive of the arms. During the first 25.0 cm of the lift, each arm exerts an upward force of 355 N on the torso. If the upward movement starts from rest, what is the persons velocity at that point?
The force on a baseball as with a bat can be more than 8,000 lb. No human can push on a bat with that much force. What is happening in this instance?
Two teams of nine members each engage in a tug of war. Each of the first team's members has an average mass of 68 kg and exerts an average force of 1350 N horizontally. Each of the second team's members has an average mass of 73 kg and exerts an average force of 1365 N horizontally. (a) What is magnitude of the acceleration of the two teams? (b) What is the tension in the section of rope between the teams?
