# A block of mass 76 kg slides along a fric- tionle…

### Question Description:

A block of mass 76 kg slides along a fric- tionless table with a speed of 50 m/s. Directly in front of it, and moving in the same direc- tion with a speed of 25 m/s, is a block of mass 41 kg. A massless spring with spring constant 1474 N/m is attached to the second block. During the collision, the spring is com- pressed by a maximum amount x. What is this maximum compression? Hint: work in an inertial frame in which p1 + p2 = 0 . Answer in units of m. The blocks will eventually separate again. What is the final velocity of the 76 kg block? Answer in units of m/s.
