Name the action and reaction forces, and identify the force that is responsible for the motion. a) A baseball bat strikes a fastball.b) A person walks across the classroom floor.c) A balloon flies erratically through the air as it deflates.d) A football player collides head-on with another player, and both players are brought to rest.e) As the driver turns the steering wheel, the car turns around a corner.arrow_forward2. Croquet is a lawn game played by hittingplastic or wooden balls with a mallet to gothrough hoops. Shown here is a diagram of a mallet striking a croquet ball, and two in-complete free body diagrams for the mallet and the ball. On the mallet, FApplied is pro-vided by the player holding the mallet, and on the ball, FMallet is the force on the ballfrom the mallet. At this moment, all motionof both objects is totally horizontal and noacceleration occurs vertically.a. The 0.5 kg croquet ball is observed to accelerate with an acceleration of a = 16 m/s2tothe right. Neglecting friction, what is the force provided by the mallet? b. Draw a new, completed free body diagram for the mallet. You do not have to includeany vertical forces. c. The mallet’s mass is 3 kg and the applied force is FA = 5 N. What is the acceleration ofthe mallet, and what direction is its acceleration?arrow_forwardEach propeller of the twin-screw ship develops a full-speed thrust of F=315 kN. In maneuvering the ship, one propeller is turning full speed ahead and the other full speed in reverse. What thrust Pmust each tug exert on the ship to counteract the effect of the ship's propellers?

- A baseball catcher is performing a stunt for a television commercial. He will catch a baseball (mass 145 g) dropped from a height of 60.0 m above his glove. His glove stops the ball in 0.0100 s. What is the force exerted by his glove on the ball?arrow_forwardTwenty people participate in a tug-of-war. The two teams of ten people are so evenly matched that neither team wins. After the game they notice that a car is stuck in the mud. They attach the tug-of-war rope to the bumper of the car, and all the people pull on the rope. The heavy car has just moved a couple of decimeters when the rope breaks. Why did the rope break in this situation when it did not break when the same twenty people pulled on it in a tug-of-war?arrow_forward(a) What force causes an automobile to move?

- Balancing carefully, three boys inch out onto a horizontal tree branch above a pond, each planning to dive in separately. The third boy in line notices that the branch is barely strong enough to support them. He decides to jump straight up and land back on the branch to break it, spilling all three into the pond. When he starts to carry out his plan, at what precise moment does the branch break? Explain. Suggestion: Pretend to be the third boy and imitate what he does in slow motion. If you are still unsure, stand on a bathroom scale and repeat the suggestion.arrow_forwardA ball is held in a persons hand. (a) Identify all the external forces acting on the ball and the reaction to each. (b) If the ball is dropped, what force is exerted on it while it is falling? Identify the reaction force in this case.

The astronaut has a few packages that she can throw away to move herself toward the ship. Construct a problem in which you calculate the time it takes her to get back by throwing all the packages at one time compared to throwing them one at a time. Among the things to be considered are the masses involved, the force she can exert on the packages through some distance, and the distance to the ship.arrow_forward

(b) Calculate the average force on the person if he is stopped by an air bag that compresses an average of 15.0 cm.arrow_forwardA baseball approaches home plate at a speed of 45.0 m/s, moving horizontally just before being hit by a bat. The batter hits a pop-up such that after hitting the bat, the baseball is moving at 55.0 m/s straight up. The ball has a mass of 145 g and is in contact with the bat for 2.00 ms. What is the average vector force the ball exerts on the bat during their interaction?arrow_forward
