1. Wear safety glasses and recruit a responsible person to observe carefully.2. Get the wooden two-by-four board and use the table saw to cut it into two 1 1/2X1/12 foot prisms. Use the remaining pine to cut out a right triangle with legs measuring 3 1/2X5 inches, with the shortest angle approximately 35°.3. Use the bit set to drill two holes two inches from the shortest edge of each prism, about three inches apart. Drill the hypotenuse and the longest leg of the triangle so that the prisms intersect at the smallest angle. Using the four screws, screw in the Phillips head wood screws.4. With scissors, carefully cut out a small two-inch by two-inch square hole while another responsible adult watches the tennis ball. Wedge it into the intersection until it is tight.5. Cut 20 inches of the half-inch elastic. Fold it on itself and sew the edges together with the attached fabric. Use the drill to make a hole the size of the indicated screw on the opposite edge from the vertex and use the screwdriver to screw it in securely. Then attach the washers to the other end. Repeat on the other board.6. Cut 15 inches of quarter-inch elastic. Sew quarter-inch elastic to the prism adjacent to the longer leg so it can energize the rotation.7. Attach the bubble lever with tape to the triangle with an elevation angle of 50°.8. Get a rope about 10 inches long. Attach it two inches from the long part of the triangle and four inches from the hypotenuse of the triangle. Use a marker or sticker to mark about two inches from the base of the longest leg. Construction of the Magnus 2.4 is completed.9. Get six plastic cups and secure them in pairs with tape. The smaller circles of the trunk should connect to each other with tape. Make sure that... in the center of the paper... make sure this doesn't happen by reading the bottom tab.32. Record the values ​​of A and B in the data graph. Please remember that C is an arbitrary constant and since we are measuring from the origin, it makes no difference to the trajectory.33. Exit the data tool and set the vertical axis to vy: y component of velocity. Resets the adaptation name to the line. Repeat step 30, only this time record it under the initial acceleration and final acceleration.34. Repeat steps 23-33 for the rest of the video files.35. If the data is recorded in a spreadsheet, use the average function to average all the information corresponding to the correct subcategories.36. Thanks to Newton's second law, you can multiply the mass in kilograms by the initial acceleration to calculate the average upward force in Newtons.37. Use a graphing calculator to graph the average parameters of parabola A and B.
