If two trains both 5 kg are moving at 10 m/s when together, but initially only one was moving, what was the first train moving at?

Two trains face each other on adjacent tracks. They are initially at rest, and their front ends are 49 m apart. The train on the left accelerates rightward at 0.87 m/s2. The train on the right accelerates leftward at 0.8 m/s2. Two trains face each other on adjacent tracks. They are initially at rest, and their front ends are 49 m apart. The train on the left accelerates rightward at 0.87 m/s. The train on the right accelerates leftward at...
You’re standing on the uOttawa LRT platform watching the trains go by. Two train-cars attached together, each 10 m long, move past you. The first takes 2.10 s to pass you and the second takes 1.65 s. What is the constant acceleration of the train?
Two ice skaters are gliding together along the ice, both moving at the same, constant velocity (sliding without exerting a force). The first skater (the one in the back), with mass M1 = 62.3 kg, pushes the second skater (the one in front), with mass M2 = 70.4 kg, directly forward in the direction they are initially moving. After the push the first skater is not moving (velocity = 0) and the second skater is moving with a velocity of...
A block having a mass of 5 kg is initially moving at a speed of 10 m/s in the positive x-direction when it experiences a head on collision with a second block having a mass of 8 kg that was initially moving in the negative x-direction with a speed of 3 m/s. After the collision the velocity of the larger, 8 kg, block is observed to be 5 m/s in the positive x-direction. The situations before and after the collision...
A 3 kg block moving at velocity 10 m/s when it collides with and sticks to another 2 kg block initially at rest, as in the fig below. How far up from ground do both blocks travel on the incline plane?
A 1.20 103 kg railroad car is traveling at 9.00 m/s when it bumps into and connects to a 0.45 10 raroad car that is moving down the tracks in the same direction but with a speed of 3.55 m/s. After they connect together they both continue on. A) What properties are conserved within this system: energy, momentum, both, or neither? B) What is the initial momentum and energy of the first car? C) What is the initial momentum and...
Two ice skaters are gliding together along the ice, both moving at a constant velocity vi = 4.39 m/s (sliding without exerting a force). The first skater, the one in the back, with mass M1 = 79.6 kg, pushes the second skater, the one in front, with mass M2 = 57.3 kg, directly forward in the direction they are initially moving. After the push the first skater is not moving (velocity = 0) and the second skater is moving with...
