The Force Table and Projectile Motion Objective The objectives of this laboratory are to learn a mechanical way to add vectors using the force table and to learn about projectile motion, including the relationship between initial velocity, initial height, and horizontal displacement.

Can you solve this prediction? Predictions: 1) Two vectors, and , are to be added together. Calculate the resultant and equilibrant vectors if = 15 N at 145 and = 10 N at -76 using any method (but show your work).

2) Beginning with our kinematic equations and the basic principles of projectile motion, derive a single equation for the initial launch velocity of a projectile that is shot horizontally out of a launcher and travels a horizontal distance x while falling a vertical distance y to the ground. Assume that we can measure the initial and final positions.
