4. A container explodes and breaks into three fragments that fly off in one plane, in directions that make equal angles apart from one another. The resulting fragments have a mass ratio 1:5:1. 4a. What kind of process is this? Show the pictorial representation of the system (i.e., show the vector momenta), and mark the known and unknown quantities that characterize this system. 4b. Show that the speeds of the first and third fragments must be equal. 4c. If the first piece flies off with a speed of 10.2 m/s, what is the speed of the second fragment?

A spring with relaxed length 0.30 m and spring constant 1.8 N/m rests horizontally on a frictionless table and is anchored frmly to a wall on one side. You press a 400 g block into the other side until the spring length is 0.16 m and then let go.   a.) What will the momentum of the block be when it departs from the spring? (Assume contact ceases when the spring is relaxed.)   b.) If the table were no longer frictionless and the block-table interface had a kinetic coeffcient of friction of 0.1 what then would the momentum of the block be when it departs from the spring?

You head to Lake Charles for a spring break and win big at roulette. You decide to spend your winnings on a motorcycle. This 1800 N bike can go from 0 to max speed in 3 seconds.a. If the bike’s change in momentum is 4600 kg m/s, what is the max speed attained? b. What average force does the bike output to attain this change in momentum?

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

On a level, frictionless air track, a 300-g puck traveling at 20.0 cm/s to the right undergoes a perfectly elastic head-on collision with a 500-g puck that is traveling to the left, directly toward the first puck, at 10 cm/s. What is the speed of the 500-g puck after the collision? a. 17.5 cm/s b. 22.5 cm/s c. 12.5 cm/s d. 20.0 cm/s e. 15.0 cm/s
