A boat travleing at 20.0m/s goes undernetath a 7.50m high bridge. As it is directly underneath the bridge, a rock from the bridge lands in the boat. Assuming that the rock fell freely from rest, Describe the initial position of the boat right as the rock fell.

a) Draw a picture of the system with the rock and the boat. Label all important information on your picture.

b) Which equation can represent the motion of the boat? Which equation can represent the motion of the rock? Which variable must be the same for both objects in this system?

c) Solve for the position of the boat in the boat/rock system right when the rock begins to fall

d) A classmate claims that the boat must travel farther than the rock over the same time period because it has a higher initial velocity than the rock. Explain what is correct and/or incorrect about the student's claim. Use evidence from your equations and calculated values.

e) A different student claims that the rock should travel less distance than the boat over the same time period because it is accelerating from rest. Explain what is correct and/or incorrect about the student's claim. Use evidence from your equations and calculated values.
