Question

1. Make a quantitative prediction for the force your body has to exert in order to hold a gallon of water, in Newtons (meaning the Force vector answer has a number in units of Newtons and a direction.) [hint: What information are you given about the water? What units is it given in? What formulas/unit conversion do you have to use to get to units of Newton’s? Google can help provide you with additional water specs if you aren’t a water expert!]

2. Consider the following scenarios:

a) A rope is tied to a fixed point on a wall. You grab the free end and lean away from it until the moment that the rope is taut.

b) You are holding one end of a rope, with a friend holding another. You lean away from your friend, also leaning like the Tower of Pisa, until the moment that the rope is taut, with your friend pulling their end of the rope keeping the it in place.

Now please choose the statement below that most closely matches your understanding of the situation. Justify your choice.

1. When the pole counters me, the tension in the rope is greater than when my labmate counters me.

2. When the pole counters me, the tension in the rope is equal to when my labmate counters me.

3. When the pole counters me, the tension in the rope is less than when my labmate counters me.​
