A railroad car of mass 3.5*10^4 kg moving at 2.50 m/s collides and couples with two coupled railroad cars, each of the same mass as the single car and moving in the same direction at 1.20 m/s.(a) What is the speed of the three coupled cars after the collision?(b) How much kinetic energy is lost in the collision? (joules)
A circus performer stretches a tightrope between two towers. He strikes one end of the rope and sends a wave along it toward the other tower. He notes that it takes the wave 0.730 s to reach the opposite tower, 20.0 m away. If a 1 meter length of ..
