Question

One of the forces in an action/reaction pair is the force of a bat hitting a ball. What is the other force in the pair? I. 2. A fly smashes into the windshield of a Mack truck that's traveling 70 mph. The impact force a) greater for the Mack truck. b) greater for the fly. c) the same for both. A fly smashes into the windshield of a Mack truck that's traveling 70 mph. The resulting acceleration is a) greater for the Mack truck. b) greater for the fly. c) the same for both. 3. A book sits motionless on a table. The normal force on the book and the force of gravity on the book are therefore equal in magnitude but opposite in direction. Do these two forces 4. make up an action/reaction pair? a) Yes ) No

Explanation / Answer

1)

The oopsite force to the action is aclled reaction so

The other force in the pair is

The force exerted by the ball on the bat

2)

the force exerted by the mack truck on fly and the fly on mack truck form an action reaction pair so they are equal

c) The same for both

3)

The foces on mack truck and fly are same but the mass of fly is much smaller than the truck and ( a = F / m)

the acceleration is

b) greater for the fly

4) The normal force and force of gravity both act on book, but

The action and reaction pair always act on two different bodies so these two force do not form action/reaction pair

b) No
