1. Wear safety goggles and recruit a responsible person to carefully watch.
2. Obtain the two by four plank of wood and use the table saw to cut it into two prisms of 1 1/2X1/12 feet. Use remaining pine to cut out a right triangle with legs measuring 3 1/2X5 inches, the minor angle being approximately 35°.
3. Use the drill set to drill two holes two inches from shorter edge of each prism, about three inches apart. Drill into the hypotenuse and the longer leg of the triangle such that the prisms intersect at the smaller angle. Using the four screws, screw in the Phillip's head wood screws.
4. With the scissors, carefully cut out a small two inch by two inch square hole with another responsible adult watching in the tennis ball. Wedge it into the intersection until it is tight.
5. Cut 20 inches of the half inch elastic band. Fold it along itself and sew the edges together with the cloth attached. Use the drill to make a hole the size of the given screw on the opposite edge from the vertex and use the screwdriver to safely screw it in. Then attach the washers to the other end. Repeat on the other plank.
6. Cut 15 inches of the quarter inch elastic band. Sew the quarter inch elastic on the prism adjacent to the longer leg so it can give spin energy.
7. Attach the bubble lever with tape to the triangle at a 50° angle of elevation.
8. Obtain a string around 10 inches long. Tape it two inches from the triangle's long length and four inches from the triangle's hypotenuse. Use a marker or sticker to mark approximately two inches from the base of the longer leg. The building of the Magnus 2.4 is complete.
9. Obtain six plastic cups and tape them in pairs. The frustum's minor circles should connect with each other with tape. Make sure they ...

...d ensure that it does not by reading the bottom tab.
32. Record the values of A and B in the data chart. Please recall C is an arbitrary constant and because we are measuring from the origin, it does not make any difference to the trajectory.
33. Exit the data tool and set the vertical axis to vy: velocity y-component. Reset fit name to line. Repeat step 30, only this time record this under start acceleration and end acceleration.
34. Repeat steps 23-33 for the rest of the video files.
35. If the data is recorded in a spreadsheet use the averaging function to average all the information corresponding to the proper subcategories.
36. Because of Newton's second law, it is possible to multiply the mass in kilograms by the start acceleration to calculate the average upwards force in Newtons.
37. Use a graphing calculator to graph the average A and B parabola parameters.
