A ball is dropped from a building of height h. Assume the ball starts from rest and that air friction can be ignored. Derive an expression for the amount of time it takes the ball to travel from h to h/2. Express your answer in terms of h and the acceleration due to gravity g.

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.

0 = 0.40 / 0 = 0

= 0.20 = 9.80 ⁄2 =?

=0 , = = 0.20 =0.50 0 0.40 ⁄

=0−122 =0−12(9.80 ⁄2)(0.50)2 =1.2
