Homework Help: Physics

Posted by Sydney on Tuesday, January 22, 2013 at 8:41pm.

A 2kg mass, initially at rest, is shot from a spring (k=550N/m) which is compressed by 1.3m. The 2kg
mass hits a stationary 6kg mass (the actual collision lasts 0.02seconds). After the collision the 2kg mass
is travelling 11m/s to the left. To the right of the 6kg mass is a rough patch that has a 0.4 coefficient of
friction. To the left of the 6kg mass there is no friction.

a. What is the distance that block two will move after the collision??
