a. Draw an interaction diagram.

b. Identify the “system” on your interaction diagram.

c. Draw a free-body diagram for each object in the system. Use

dashed lines to connect members of an action/reaction pair.

Short answer

a. The interaction diagram is :

b. The system has soccer ball and basketball as constituents.

c. The free body diagram is :

Step-by-step solution

Part (a) Step 1 : Given information

A soccer ball and a bowling ball have a head-on collision.

Rolling friction is negligible.

Part (a) Step 2 : Calculation

There are three types of interactions provided in this case.

Interaction between the soccer ball and basketball, interaction between the two balls and surface and interaction between the earth and the balls.

Interaction diagram is given below :-

Part (a) Step 3 : Final answer

The interaction diagram is :

Part (b) Step 4 : Given information

A soccer ball and a bowling ball have a head-on collision.

Rolling friction is negligible.

Part (b) Step 5 : Calculation

System is defined as the space which constituent all the constituent participating.

The system here consists of basketball and soccer ball.

Part (b) Step 6 : Final answer

The system has soccer ball and basketball as constituents.

Part (c) Step 7 : Given information

A soccer ball and a bowling ball have a head-on collision.

Rolling friction is negligible.

Part (c) Step 8 : Calculation

Normal force 'n' is acting on an upward on basketball (BB) and there will be forced due to gravity, which is W_bb is acting opposite to the normal force and the force due to soccer ball on basketball which is $F_{sb}\text{on}bb$in the above diagram.

Very similarly there is the force acting on soccer ball due to basketball which is $F_{bb}\text{on}sb$.

Normal force will act perpendicular to the colloidal axis and there will be forced due to gravity, which is opposite to the normal force n.

Part (c) Step 9 : Final answer

The free body diagram is :
