Calculate the momentum before and the momentum after and find the change in momentum. SHUD SAJ-394 2. Compare the change in momentum (A momentum) to the impulse (area under the curve). 3. Calculate the percent difference of the change in momentum (Amv) and the impulse. HD ON NEW VOY Amv - impulse %diff = x 100% Amv + impulse 4. Look at the shape of the last force vs. time graph. Is the peak value of the force significantly different from the average force? Is there a way you could deliver the same impulse with a much smaller force? 5. Revisit your answers to the Pre-Lab Questions in light of your work with the impulse-momentum theorem. 6. When you use different elastic materials, what changes occurred in the shapes of the graphs? Is there a correlation between the type of material and the shape? 7. When you used a stiffer or tighter elastic material, what effect did this have on the duration of the impulse? What affect did this have on the maximum size of the force? Can you develop a general rule from these observations?Impulse and Momentum The impulse-momentum theorem relates impulse, the average force applied to an object times the length of time the force is applied, and the change in momentum of the object: FAt = mvf - mvi Here we will only consider motion and forces along a single line. The average force, F , is the net force on the object, but in the case where one force dominates all others it is sufficient to use only the large force in calculations and analysis. For this experiment, a dynamics cart will roll along a level track. Its momentum will change as it reaches the end of an initially slack elastic tether cord, much like a horizontal bungee jump. The tether will stretch and apply an increasing force until the cart stops. The cart then changes direction and the tether will soon go slack. The force applied by the cord is measured by a Force Sensor. The cart velocity throughout the motion is measured with a Motion Detector. Using the calculator to find the average force during a time interval, you can test the impulse-momentum theorem. side Tenofsit Motion Detector Force Sensor Elastic cord Figure 1 OBJECTIVES .

In a car collision, the driver's body must change speed from a high value to zero. This is true whether or not an airbag is used, so why use an airbag? How does it reduce injuries? 2. You want to close an open door by throwing either a 400 g lump of clay or a 400 g rubber ball toward it. You can throw either object with the same speed, but they are different in that the rubber ball bounces off the door while the clay just sticks to the door. Which projectile will apply the larger impulse to the door and be more likely to close it? PROCEDURE 1 . Design a laboratory procedure where you can collect the following data: Final Velocity of the cart, the initial velocity of the cart, the impulse delivered to cart by the elastic cord
