Question 1, chap 11, sect 2. part 1 of 1 10 points A 0.451 kg bead slides on a straight fric tionless wire with a velocity of 4.58 cm/s to the right, as shown. The bead collides elas tically with a larger 0.626 kg bead initially at rest. After the collision, the smaller bead moves to the left with a velocity of 0.66 cm/s. . 451 kg 4 . 58 cm / s . 626 kg Find the distance the larger bead moves along the wire in the first 4.9 s following the collision. Answer in units of cm. Question 2, chap 11, sect 2. part 1 of 2 10 points Consider the collision of two identical par ticles, where the initial velocity of particle 1 is v 1 and particle 2 is initially at rest. 1 2 v 1 After an elastic headon collision, the final velocity of particle 2 v 2 is given by 1. v 2 = 2 v 1 2. v 2 = v 1 3 3. v 2 = 4 v 1 3 4. v 2 = v 1 4 5. v 2 = 0 6. v 2 = 3 v 1 4 7. v 2 = v 1 8. v 2 = 5 v 1 3 9. v 2 = v 1 2 10. v 2 = 2 v 1 3 Question 3, chap 11, sect 2....
