A block of mass m 1 = 2 kg slides along a frictionless table with a speed
Question:
A block of mass m1 = 2 kg slides along a frictionless table with a speed of 10 m/s. Directly in front of it, and moving in the same direction with a speed of 3 m/s, is a block of mass m2 = 5 kg. A massless spring with spring constant k = 1120 N/m is attached to the second block as in Figure
(a) Before m1 runs into the spring, what is the velocity of the center of mass of the system?
(b) After the collision, the spring is compressed by a maximum amount Δx. What is the value of Δx?
(c) The blocks will eventually separate again. What are the final velocities of the two blocks measured in the reference frame of the table?
