Part 2: Conservation of Momentum In this section, you will show that momentum is conserved for an elastic collision and for an inelastic collision. Remove the force sensor from the cart, then set up a motion sensor about 30cm from each end of the track and bring up a velocity vs. time graph for each. Place the other black plastic "foot" on the track and level it. Set the sampling rate of each motion sensor to 20 Hz. Experiment 1: Inelastic Collision 1) Write a momentum conservation equation for an inelastic collision between two carts. Identify the total initial momentum of the system and the final momentum of the system. Set up the following: Add 0.25 kg to Cart 1 so that its mass is 0.5 kg. It starts with v₁. Don't add mass to Cart 2 (its mass is 0.25 kg). It starts at rest. The velcro of one cart must face the velcro of the other. Start data collection. Give Cart 1 a quick push and let go. Let it collide with Cart 2. Record the following and make all velocities positive: V₁ = V₁ = m/s m/s
Calculate the following: Total initial momentum of the system: Total final momentum of the system: |Py-Pil PL (Must be <= 15%!) % difference between pi and pr=- x 100 = Part 2: Conservation of Momentum Ns NS % Experiment 2: Elastic Collision 1) Write a momentum conservation equation for an elastic collision between two carts. Identify the total initial momentum of the system and the final momentum of the system.
Set up the following: Add 0.50 kg to Cart 1 so that its mass is 0.75 kg. It starts with v₁. Add 0.25 kg to Cart 2 so that its mass is 0.50 kg. It starts at rest. The magnets of one cart must face the magnets of the other (no Velcro). Start data collection. Give Cart 1 a quick push and let go. Let it collide with Cart 2. Record the following and make all velocities positive: V₁ = V₁ = V2f = Calculate the following: m/s m/s m/s Total initial momentum of the system: Total final momentum of the system: |pg-Pil Pi (Must be <= 15%!) % difference between pi and p = x 100 = Ns NS %
