Now that you’ve verified that you know how to make a measurements from this video. Let’s analyze both carts. Use the roller and stopwatch to measure the velocity of each car for the first 30 cm of motion immediately after their hands are no longer in contact. 3. Calculate the momentum of Christine and her cart Asher rules immediately after they are no longer in contact. p=mv 4. Calculate the momentum of Deamon and his cart as he rules immediately after they are no longer in contact. 5. Calculate the total war mentum of the system comprising The two cards and the two people. Data given: Christines cart has a mass of 60 kg Daemon cart has a mass of 66.5 kg The carts have a mass of 22 kg each The velocity closest to daemons cart is V= 1.2 m/s Measured with a ruler at 30 cm apart the time is 0.8875 s.
