Amolecule of mass 2.0x10-24 kg is moving with a speed of 100+10 m/sec, i. e., with an indeterminacy of +10 m/sec on its velocity. a. what is the minimum indeterminacy ax on its position? b. what is the de broglie wavelength of this molecule? c. what is the (non-relativistic) kinetic energy of this molecule? d. suppose this molecule has a wave function given at t=0 by p(x,0)=a sin (270/2.) what is the probability density at x = 14 (in terms of a)? e. suppose this molecule has a spin quantum number s = 5/2. find the magnitude s its spin angular momentum as well as the possible values of its z-components. draw vector diagram showing the possible orientations of this spin angular momentum.

Rebekah has a table that has a mass of 21.7 kg. what is the weight of the table? a. 6 n b. 31.5 n c. 9.8 n d. 212.66 n

A33.1 g copper object is launched from a 1.5 m 30° steel incline positioned on the floor by being pulled up a string attached to a 50.0 g mass suspended vertically over a pulley. the object is projected towards a glass table where it lands when it is at the point along its trajectory with the lowest speed. it comes to a halt when it clears the opposite edge of the table. it then falls and lands on 9 physics texts each 5 cm thick that are stacked on the floor on the opposite side of the table. assume that the table does not have a ledge and the rectangular object experiences 0.05 n of air resistance as it falls towards the books. how far and how long did the object travel and how fast does it hit the books. assume that at the moment the copper object leaves the incline, the massless string and ideal pulley break off
