    Projectile egg target lab

    Purpose:

    1. Observe and understand motion of a projectile launched horizontally. 2. Apply kinematics equations to data to determine the time of flight, velocity with

    which the ball left the table, and the acceleration on the ramp. 3. Use information from part 1, and understanding of physics to predict where the

    ball will land when started from a new initial position.

    Materials:

     Piece of angle iron

     Steel ball

     Flat table

     Meter stick

     Carbon paper

     Egg

    Part 1

    Procedure:

    1. Set up your angle iron to form a ramp approximately 5cm from the end of the

    table. Be sure to set it up in a way that can be exactly replicated tomorrow. 2. Mark a point exactly half way up your ramp. Place your ball on the point. 3. Allow the ball to roll down the ramp, onto the table, off the table and onto the

    floor.

    4. Estimate the landing spot. Tape a piece of computer paper to the floor so that the

    center is approximately where the ball landed. Lay a piece of carbon paper on top

    of the paper.

    5. Set the ball on the half-way point and release 3 more times (Each time make sure

    that a team member catches the ball immediately after it hits so that it does not

    bounce and land on the carbon paper a second time.). The carbon paper should

    mark the location. Measure the distance from a point on the floor directly below

    the end of the table to the landing point of the ball. Record this distance as d= __ x

    6. Measure and record the height of the table. Record this distance as d =_____ y

    7. Give the ball to Mrs. Mann.

    8. Draw a free body diagram of the ball just as it leaves the table.

9. What is the net force in the x direction?

10. What is the acceleration in the x direction?

11. What is the net force in the y direction?

12. What is the acceleration in the y direction?

    13. Use the free body diagram, your understanding of physics, and the table below to

    determine the time that the ball was in the air. Show all formula and substitutions

    with units!

    This page is about the ball leaving the table and traveling to the floor after rolling half

    way down the ramp.

    14. Use the rest of the information in the table to determine the velocity with which

    the ball left the table. Show all formula and substitutions with units!

    This section is about the ball rolling along the table after traveling half way down the ramp.

    15. Draw a free body diagram of the ball as it rolls along the horizontal table. (It

    rolled for such a short distance that friction is negligible.)

    16. Based upon your free body diagram, what is the net force on the ball as it rolls

    horizontally along the table?

    17. What is the acceleration of the ball as it rolls horizontally along the table?

18. With what speed did the ball leave the ramp?

This section is about the ball rolling half way down the ramp.

19. Draw a sketch of the ball on the ramp.

    20. Indicate the direction of the net force (You do not need a free body diagram. You

    do not need to identify all of the forces acting on the ball).

    21. Is the ball a projectile as it travels down the ramp? Why or why not?

    22. What is the initial velocity of the ball when it is first released from the point

    halfway up the ramp?

23. What is the final velocity of the ball as it leaves the ramp?

24. What is the distance the ball travels on the ramp?

25. What is the acceleration of the ball on the ramp?

    Part 2:

    26. If the same ball is rolled from a higher location on the same exact ramp, then the

    net force acting on the ball will be

    a. More

    b. Less

    c. The same

    27. If the same ball is rolled from a higher location on the same exact ramp, then the

    acceleration of the ball will be

    a. More

    b. Less

    c. The same

    28. Determine the velocity with which the ball will leave the ramp if released from

    the top of the ramp.

    29. Determine where the ball will land if the ball is released from the top of the ramp,

    allowed to roll freely along the table and project onto the floor. Show all formulas

    and substitutions with units.

30. Mark the target location, and place an egg on the target.

    31. Request your ball.

    32. You get one shot for an ice pop.
