Record the height (Y_0) of the projectile and find the corresponding time of flight using the equation t=√(2Y_0)/9.8. Place the plastic ball into the launcher and use the push rod to load the ball until the “3rd click” is heard. Press the Start button on the Smart Timer and pull the launch cord. Record the horizontal distance (X) traveled by the projectile and the time from the Smart Timer. Repeat steps 2-4 five times. The spacing between the photo gates is d= 0.1m. Find the average of these distances and then determine the initial velocity with the time calculated in step 4. Find the average time and then calculate the real velocity.
