A block of mass m1 = 1.60 kg initially moving to the right with a speed of 4.00 m/s on a frictionless horizontal track collides with a spring attached to a second block of mass m2 = 2.10 kg initially moving to the left with a speed of 2.50 m/s, as shown in Fig. a. The spring constant is 600 N/m. a) Find the velocities of the two blocks after the collision. b) During the collision, at the instant block 1 is moving to the right with a velocity of + 3.00 m/s, as in Fig. b, determine the velocity of block 2. c) Determine the distance the spring is compressed at the instant. d) What is the maximum compression of the spring during the collision?
