Analyze the Data
1. Use the statistics function of Science Workshop to determine the maximum velocity of the
cart.
2. Determine the mass of the cart
3. Calculate the momentum of the cart.
4. Use the statistics function to integrate the area under the curve.
5. Select the portion of the curve that represents the impact and record the integrated value.
ä Note: Select by clicking and dragging a box around the desired area.
6. Compare the magnitudes of the momentum of the cart and the impulse of the collision.
Question
1. Does your experimental data show that the momentum of the cart equals the impulse of the
collision? (Does mv = Fdt
t1
t2
?)
7. Drag and drop a Graph display icon to the Force Sensor icon.
Collect the data
1. Hold the cart in place close to the RMS and elevate the track using the wooden block.
2. Begin recording data.
3. Release the cart, allowing gravity to be the sole force of acceleration.
ä Note: If the impact is not completely inelastic (the cart bumps back
from the clay stopper), repeat using a smaller angle of elevation.
4. Stop recording.
