A group of physics students are on a bridge that is an unknown distance above the river below. They are dropping objects from the bridge platform and recording their results. Answer the following questions about their experiment.

1. The students want to calculate how high the bridge is above the water. They are able to measure time accurately to the tenth of a second. How will this limit the precision of their height calculations?
It should make the height very precise along as they have speed.

2. The students measure that it takes an object approximately 3.1 seconds to travel from the bridge to the water below. What is the height of the bridge?


3. For the second part of the project, the students attach small paper parachutes to the objects. They find that the larger the area of the parachute, the longer it takes the objects to reach the water below. What is the qualitative relationship exhibited?

4. The students want to draw a graph showing the velocity of the object with respect to time. What will the graph’s shape and slope be?
