It is reported that Galileo (circa 1590) dropped balls of diFerent mass at the same time from the top of the Leaning Tower of Pisa in order to demonstrate that: a) the heavier ball hit the ground ±rst by a large margin. b) the lighter ball hit the ground ±rst by a large margin. c) both balls hit the ground at more or less the same time. d) the balls would levitate toward the Moon. e) the Leaning Tower was leaning. 002 qmult 00540 1 3 2 easy math: ball thrown down Extra keywords: physci KB-60-17 36. A ball is thrown downward at 12 m / s. About what is its SPEED 2 . 0 s later assuming no air drag? a) 20 m / s. b) 32 m / s. c) 22 m / s. d) − 2 m / s. e) 12 m / s. 002 qmult 00550 2 3 4 moderate math: kinematic equations: arrow ²ight 1 Extra keywords: physci 37.
