Part B  Inelastic collision of unequal masses
1. Add a mass to cart 2 and repeat the data collection and analysis sections.
➤ Note: You will need to redefine the calculations in the Experimental
Calculator for Total Momentum and Total KE in Graph display with the
new mass values.

Questions
1. How did the inelastic collision effect the total momentum and total kinetic energy in the
system?
2. What effect did friction have on the momentum and kinetic energy of the system?
3. What are other possible contributors to the variation of the experimental data from the
expected (theoretical) values?
