  1. Two railroad boxcars are initially in motion to the right along the same straight track. The ratio of the masses of the two cars is m1/m2= (1/2). The rear boxcar m1, has a velocity twice as great as the forward boxcar, m2. The faster-moving car m1, overtakes the other car and collides with it. After the collision, what is the velocity of each boxcar if the collision is elastic?

A railroad freight car, mass 20 000 kg, is allowed to coast along a level track at a speed of 2.0 m/s. It collides and couples with a 50 000-kg loaded second car, initially at rest and with brakes released. What percentage of the initial kinetic energy of the 20 000-kg car is preserved in the two-coupled cars after collision? Question 10 options: 14% 23% 29% 31%

A single railroad car collides elastically with two other coupled cars, each of them of the same mass as the single car. Just before collision, the single car is moving with a speed of 4.0 m/s and the coupled cars are stationary. After the elastic collision, the single car recoils back and the coupled cars take off in the opposite direction. If the coefficient of kinetic friction between the railroad cars and rail track is 0.15, how far will the...

Two carts are rolling to the right along the same level track. Cart 1 (m1 = 3.81 kg) is in the rear, rolling at a speed of 6.25 m/s and catching up to cart 2, rolling at 3.07 m/s. Round final results to 3 digits. a) Cart 1 of course overtakes and collides with cart 2. Velcro pads on the carts make them stick together during the collision, after which they both continue rolling right, but at a speed of...

Two carts are initially moving to the right on a low-friction track, with cart 1 behind cart 2. Cart 1 has a speed twice that of cart 2 and so moves up and rear-ends cart 2, which has twice the inertia of cart 1. Q1: Suppose that the the initial speed of cart 2 is vv. What is the speed of cart 1 right after the collision if the collision is elastic? Express your answer in terms of v. Q2:What...

While stuck at a railroad crossing, you notice a full train car (m1 = 9000kg) is moving to your left with a speed of 9m/s. Two seperated empty train cars (m2 & m3 = 3000kg each) are on the same track moving to the right, each with a speed of 3m/s. There are two succesive collisions. First m1 and m2 hit and stick together. That pair (m1 & m2) then runs into m3. In this second collision, the air bag...
