Activity 2 My Two Dimensional Motion Along An Incline! Procedure: 1. Get a retractable pen as a launcher. Also, prepare a 1/8 illustration board or the like (any available at home). This will serve as the incline. Further, prepare a plastic bottle cap which serves as the projectile and stopwatch for time recording and ruler to measure the range. 2. Using a protractor, measure 15° angle from the floor to the incline plane. Use books to elevate the incline. Then position your launcher (retractable pen) on top (almost at the edge of the board) of the incline pointing the plastic bottle cap. (See set -up) 3. Firmly hold the retractable pen pointing the bottle cap and give a click. The cap will then have its flight. Observe the height and range of the projectile. Record on the table. Use stopwatch to record time the projectile reached the ground and compute for the height (h=1/2agt²), where ag = 9.8m/s². Do three (3) trials. 4. Repeat procedure 2&3. This time elevate the incline in the angle of 30°, 45°, 60°, & 75°.
