1. On planet Pouch, the residents travel by high speed trains that run on air tracks much like the air track you used in lab. A train car with a mass of 8700 kg is traveling at 11.0 m/s when it strikes a second car moving in the same direction at 2.2 m/s. The two stick together and move off with a speed of 4.00 m/s. What is the mass of the second car? Explain your reasoning.
2. How much kinetic energy was lost in the collision?

PHYS 1408 Lab Homework --Momentum and Collisions This homework is due when you come to lab the week of March 23 1. On the planet Microid, trains that run on air tracks much like the air track you used in lab are the principle means of transportation. A train car with a mass of 6300 kg is traveling at 12.0 m/s when it strikes a second car moving in the same direction at 2.2 m/s. The two stick together and...

Two trains approach each other on separate but adjacent tracks. Train 1 is traveling at a speed of 35.9 m/s and train 2 at a speed of 27.6 m/s. If the engineer of train 1 sounds his horn which has a frequency of 520 Hz, determine the frequency of the sound heard by the engineer of train 2. (Use 343 m/s as the speed of sound. Enter your answer to the nearest Hz.)

Two trains on separate tracks move toward one another. Train 1 has a speed of 110 km/h, train 2 a speed of 85.0 km/h. Train 2 blows its horn, emitting a frequency of 500 Hz. What is the frequency heard by the engineer on train 1? (Assume the speed of sound is 345 m/s.)

An air-track cart with mass m1 = 0.440 kg and initial speed v0 = 1.10 m/s collides with and sticks to a second cart that is at rest initially. If the mass of the second cart is m2 = 0.320 kg, how much kinetic energy is lost as a result of the collision?

Two trains are traveling on the same track and in the same
direction. The first train, which is behind the second train, blows
a horn whose frequency is 269 Hz. The second train detects a
frequency of 290 Hz. If the speed of the second train is 13.7 m/s,
what is the speed of the first train?
I used the following equation and set Fo to 290Hz and Fs to
269hz. + on top and - on bottom. I figured...

Block 1, of mass m1 = 3.50 kg , moves along a frictionless air track with speed v1 = 11.0 m/s . It collides with block 2, of mass m2 = 43.0 kg , which was initially at rest. The blocks stick together after the collision. What is the change ΔK=Kfinal−Kinitial in the two-block system's kinetic energy due to the collision?
