Anyone answer the 3 questions?
Experiment:
Tie one end of the fishing line to a chair.
String the other end of the fishing line through the straw andtie the line to a 2nd chair spaced ft. away.
Inflate the balloon. Hold it closed with your fingers, and tapeit to the straw.
Slide the straw/balloon back so that the mouth of the balloon isfacing the nearest chair.
Let go of the balloon and observe what happens.
Questions:
1. Explain what caused the balloon to move in terms of Newton's3rd Law.
2. What is the force pair in this experiment? Draw a free bodydiagram (FBD) to represent the unbalanced) forces on theballoon/straw combination.
3. Add some mass to the straw by taping some metal washers tothe bottom and repeat the experiment. How does this change themotion of the assembly? How does this change the FBD?
