Homework Help: Physics

Posted by Lilly on Monday, March 5, 2012 at 12:40am.

Two blocks, each with a mass = 0.168 kg, can slide without friction on a horizontal surface. Initially, block 1 is in motion with a speed = 1.28 m/s; block 2 is at rest. When block 1 collides with block 2, a spring bumper on block 1 is compressed. Maximum compression of the spring occurs when the two blocks move with the same speed, /2 = 0.640 m/s. If the maximum compression of the spring is 1.55 cm, what is its force constant?
