Procedure: Using your catapult, place a small projectile in the box. Pull the catapult arm all the way back until it touches the base. Release the catapult and measure the distance from the front of the catapult to the place where the object first lands. Repeat 5 times to get an accurate distance. Repeat the same procedure, but now measure the maximum height of the projectile. Repeat 5 times to get an accurate height.

 

 

 

 

Calculate the velocity of the projectile in the x and y direction and then calculate the velocity and direction of the projectile.
