- The % difference is messed up, don't know what I'm comparing... Chris Kalimtzis MARAN ABAID Ivan Group 10
 * LAB: Impulse of a softball**

Objective: Determine how the impulse of the box will compare to the impulse of the softball. Hypothesis: They will be equal. Calculations:

the mass of the softball (kg) = .181 kg the mass of packed box (kg) = 1.5 kg the total mass of packed box and softball (kg) = 1.681kg

Observation: we observed that the slower the ball was on the box, the higher the percent diffrence it was. also, the speed of the ball determins the distance the bow went back.

Equipment used: cardboard box packing material (paper) big softball meter stick, masking tape spring scale electronic balance photo gate and photo gate tape, USB link, Laptop

Discussion Questions:

1. We assumed that the speed was constant on the balls journey. 2. You can find the initial velocity using kinematics and dynamics. 3. If you cant find impulse you can find momentum. 4. 150J I had a hard time reading the graph times. 5. 150 The same as the impulse. 6. -10 m/s 7. 5000J
