A block of mass 9.1 kg rests on a horizontal frictionless floor, and is connected to a vertical wall by a spring of force constant 205 N/mN/m as shown in the figure. When the spring is in its equilibrium position (neither stretched nor compressed), the block just touches a second lighter block of mass 3.4 kg at rest on the frictionless floor. The spring is now compressed by 0.12 mm (only the heavier mass is moved towards the wall) and then released. The heavy block collides with the stationary lighter block and the two blocks stick together after collision

Part A) What is the speed of the heavier block just before the collision? (three sig figs)

part B) What is the speed of the combined blocks just after the collision? (two sig figs)

part C) What is the maximum stretch of the spring after the collision? (two sig figs)

Part D) What is the time period of subsequent oscillations?(two sig figs)
