An object of mass m1=0.410kg starts from rest at point A and slides down an incline surface that makes an angle of 25.0° with the horizontal. The coefficient of kinetic friction between the object and the incline surface is 0.395. After sliding down a distance d=6.50m, it makes a perfectly inelastic collision with an object of mass m2=0.630kg at point B.

A) Find the speed of m1 at point B just before the collision

B) Find the energy loss during the collision. Enter the magnitude

C) After the collision, the objects travel on a horizontal surface with a kinetic coefficient of 0.430. How long does it take until the objects come to rest at point C?

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?

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...
