Question 11 Three blocks slide on a smooth surface, as shown in Figure A2.11. Initially, the first block (m₁ = 1.0kg) moves at 3.0m/s to the right, the second block (m2 1.0kg) moves at 3.0m/s to the right, the second block (m₂ = 2.0kg) is at rest, and the third block (m3 = 3.0kg) moves to the left at 0.50m/s. First, m₁ 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. Question 12 A billiard ball moves at a speed of 4.00m/s and collides elastically with an identical stationary ball. As a result, the stationary ball flies away at a speed of 1.69m/s, as shown in Figure A2.12. Determine a. the final speed and direction of the incoming ball after the collision. b. the direction of the stationary ball after the collision.
