Block m, of mass 15 kg moving with velocity v = 33 m/s on a frictionless plane collides block mą which is connected to block m3 by a long, massless spring with spring constant k = 7000 N/m: see the figure.

B and C assume that the collision of blocks m, and my is completely inelastic. (Because the spring is relaxed before the collision, block mg does not move at the instant of impact therefore (m, +m2) must move through a finite displacement before any force acts on mg and cause it to move.) For parts D and E assume that the collision of blocks m, and m2 is elastic. (Because the spring is relaxed before the collision. block mg does not move at the instant of impact. therefore mą must move through a finite displacement before any force acts on mg and cause it to move.)

• For parts A. B and C assume that the collision of blocks m; and m2 is completely inelastic. (Because the spring is relaxed
before the collision, block mg does not move at the instant of impact therefore (m, +m2) must move through a finite
displacement before any force acts on m3 and cause it to move.)
• For parts D and E assume that the collision of blocks m, and mą is elastic. (Because the spring is relaxed before the
collision. block mg does not move at the instant of impact therefore mą must move through a finite displacement before any
force acts on mg and cause it to move.)
D) After the collision. what is the speed of block m, in units of meters per second?
