Which of the following examples contains an uncontractible copula?

A mover is applying a force on a crate up an incline. The incline is slightly rough with a coefficient of kinetic friction of 0.150. If the piano is not accelerating, that is, moving up the incline with constant speed, what is the magnitude of the work done by the mover if the incline is 3.00 m long and the piano has a mass of 180 kg. The angle of the incline is 10.00. Use three significant digits please. 

An object of mass 100.0 kg moving “east” with 25.0 m/s collides head-on and sticks to an object of 250.0 kg moving “west” with 20.0 m/s. What is the magnitude of the final speed of the composite? Use three significant digits.

Assume a particle at point “A” starts from rest and then travels down a non-frictionless ramp. It then travels horizontally along a frictionless surface and compresses a spring 0.28 m. If the spring constant of the spring is 200 N/m, the length of the ramp is 4.0 m, and the mass of the particle is 1.0 kg, calculate the magnitude of the work done by friction on the particle while it was on the incline. Use three significant digits.  

Momentum is always conserved when dealing with two particle collisions just before and just after the collision.

If the total (initial) momentum of a two-particle system is zero, then this means just after an internal interaction the particles will travel in opposite directions.
