Two Train Cars 1 2 3 4 5 6 M A Train Car With Mass M 577 Kg Is Moving To The Right With A Speed Of V 7 M S And Co 1 (27.33 KiB) Viewed 61 times
Two Train Cars 1 2 3 4 5 6 m₁ A train car with mass m₁ = 577 kg is moving to the right with a speed of v₁ = 7 m/s and collides with a second train car. The two cars latch together during the collision and then move off to the right at v; = 4.4 m/s. 1) What is the initial momentum of the first train car? 2) What is the mass of the second train car? m₂ kg-m/s Submit m₁ kg Submit 3) What is the change in kinetic energy of the two train system during the collision? Submit m₂ Now the same two cars are involved in a second collision. The first car is again moving to the right with a speed of v₁ = 7 m/s and collides with the second train car that is now moving to the left with a velocity v₂ = -5.1 m/s before the collision. The two cars latch together at impact. What is the final velocity of the two-car system? (A positive velocity means the two train cars move to the right - a negative velocity means the two train cars move to the left.) m/s Submit
5) Compare the magnitude of the momentum of train car 1 before and after the collision: P1 initial P₁ initial P1 initialP1 final Submit P₁ final > P₁ final (Survey Question) 6) Below is some space to write notes on this problem Submit +
