I already solve for the velocity and the time in the both case. Can you explain and do the 3rd part? 3. Sketch a diagram and clearly label x- and y-axes, and the (x,y) coordinates of initial position and final position. Show calculations below. Discuss sources of experimental error. Attach additional pages if necessary.

Projectile Motion Lab The purpose of this lab is to determine the launch velocity of a projectile. del girl To bearing ad Use the spring launcher to launch the ball horizontally off the table. Record the initial and final positions of the ball and determine the initial launch velocity of the ball without using a timer. Sketch a diagram and clearly label x- and y-axes, and the (x,y) coordinates of initial position and final position. Show calculations below. Discuss sources of experimental error. Attach additional pages if necessary.
