Object 1, with mass m1 and speed 5.3 m/s, slides along on a frictionless ice rink and then undergoes
a one-dimensional elastic collision with a standstill object 2, with mass m2 = 0.44m1. The two objects
then slide into a region where the coefficient of kinetic friction is 0.56; there they stop. How far into that
region do (a) object 1 and (b) object 2 slide? (c) Assume the collision is inelastic, and that the objects
stick together. How far does the combined object slide into the region?

An object of mass m1 approaches with velocity v1 another object of mass m2, which is at rest, next to a spring having force constant k. The spring is fixed to a wall and m2 can compress the spring. This is one-dim horizontal collision without friction. We consider two collision scenarios, one which is perfectly inelastic, and the other which is elastic. (a) In the first collision case the object m1 strikes m2 and sticks. Moving together, they compress the...
