Document Summary
Score: 0. 333 v0, 0. 5 v0, 0. 667 v0, elastic, inelastic. I = (1/3) m l2 solid sphere: solid cylinder or disk (rotated about axis of symmetry): hoop or thin ring (rotated about axis of symmetry): thin rod, rotated about center: thin rod, rotated about end: You may use calculators and both sides of 2 pages of notes, handwritten only. For multiple choice questions, circle the one best answer or letter (unless more than one answer is asked for). Some moments of inertia: a. (2 pts. ) A mass 2m moving at speed v0 collides head-on with another mass m initially at rest. If the masses can move only along the x-axis, what is their final speed after collision? (ignore friction. : (1 pt. ) The collision in part (a) is: a 150-gram baseball traveling to the left at 45 m/s is hit by a bat. The ball leaves to the right at high speed: (2 pts. )
