1/31

Objective:  SWBAT review for Friday's test.  (Yes it's Friday, not Thursday.)

Warm Up:  Labs turned in or emailed?
A block of mass 1.6 kg is moving to the right with a speed of 4.0 m/s on a frictionless track when it collides with a second block of mass 2.0 kg, attached to a spring.  The second block is moving to the left at a speed of 2.5 m/s.  The spring's constant is 600 N/m.  At the instant the first block is moving with a speed of 3.0 m/s to the right, determine the velocity of block 2.
