Three blocks slide on a smooth surface, as shown in Figure A2.11. Initially, the first block (m1 = 1.00 kg) moves at 3.00 m/s to the right, the second block(m2

= 2.00 kg) is at rest, and the third block (mg = 3.00 kg) moves to the left at 0.500 m/s. First, m, collides elastically with m2 and recoils to the left. Afterwards, m2 and m3 collide and stick. Calculate, a. the velocities of m1 and m2 after the first collision. b. the velocity of m2 and m3 after the second collision.
