IV7 Homework
*Complete the analysis for the motion of both balls.

3. Find the initial velocities for both balls the instant they leave the trough.
Remember both velocities may have vertical and horizontal components.

4. Find the initial accelerations of both balls. Remember both accelerations
may have vertical and horizontal components.

5. Find the final velocities for both balls just before they hit the floor.
Remember both velocities may have vertical and horizontal components.

6. Do the balls experience a drag force? Justify your answer from your data.

7. Write a summary description of the motion of the two balls. How are
these motions the same? How are they different?

Give vector equations of motion for acceleration, velocity and displacement
as functions of time for both balls. State your starting time and describe
the coordinate system you are using.
