Two atoms collide while moving in a dilute gas. The larger atom has a mass M₁ = 6 Daltons and a speed v₁ = 200 m/s, while the smaller has a mass M2 = 1 Daltons. During the collision both atoms simply bounce off each other. They do not change their speeds, but after the collision they each change their directions, bouncing in the indicated directions. Gravity can be ignored during the collision. A. What is the direction of the change in the momentum of the smaller atom? Use the letters from the compass rose below the figure to specify directions. B. Which of the following statements are true about the momenta of the two atoms? 1. The change in the momentum of M2 has the same magnitude as the change in momentum of M1. 2. The total change in the momentum of M1 and M2 must be zero. 3. The total momentum of M1 and M2 must be 0. 4. Because the angles are not the same, the collision cannot take place as described. C. What is the magnitude of the change in momentum of M₂? M₁ M₂ G F 90° E E B K

Frosty the Snowman’s magic hat keeps him at a comfortable temperature of -11°C. However, a nearby test of a nuclear explosive device knocks off his hat and irradiates him. He absorbs 47 MJ of energy! Frosty’s initial mass is 99 kg of pure ice. Ignore the hat and any other ornaments. We need to determine if Frosty absorbs sufficient energy to melt completely. What is the minimum amount of energy, in megajoules, that is required to melt Frosty?

Quantitative Analysis - Introducing Elasti For each of the following situations: a. Choose an initial and final state (states A and B) that will be appropriate (interesting) for analysis. b. If there is not already a physical diagram of the situation and there should be one for proper analysis, include one. c. Construct a system schema of the situation. Do not forget to include the system boundary for the system specified by the problem. Choose your system wisely. d. Construct an energy bar chart and system flow diagram (LOL plots) for each problem. e. You are allowed to add other energy storage modes. You do not have to use the energy storage modes that are printed in each LOL plot. f. Find the unknown value. 1.
