( I added 3 distances travelled and got average
113.4 cm 114.3 cm 115.5 cm and divided by 3 got 114.4 and concerted to m which is 1.144 M.)
i need help finding velocity, with work shown!

Projectile Motion Experiment Objective: The objective is to study projectile motion and to determine the initial velocity of a spring projectile launcher using appropriate kinematics equations and data for range and height of fall. Apparatus: Projectile launcher, 25mm plastic ball, meter stick, tape measure, paper, lab jack, table clamp. Procedure: Part A Place the spring projectile launcher on the table set for horizontal (0°) and clamp the base so that muzzle is at the edge of the table. Put the yellow ball in the launcher and cock it to the maximum range position using the ram rod. Fire the ball once to note where it strikes the floor, then tape a piece of paper over that spot so that the landing position of the ball may be found for future firings. Now fire the ball three times hitting the paper and note the center of the pattern on the paper. Measure the height of the ball at the point where it leaves the muzzle, and the range (horizontal travel distance) using the tape measure, from the point directly below the point where the ball leaves the launcher. Using the appropriate kinematics equations, calculate the muzzle velocity of the ball. Use the average value of the horizontal range for the three shots.
