Avolleyball starts from rest and accelerates with an acceleration of 0.415 m/s2 while moving down a 9.00 m long inclined plane. when it reaches the bottom, the ball rolls up another plane, where, after moving 14.50 m, it comes to rest.
a) what is the speed of the ball at the bottom of the first plane?
m/s
b) how long does it take to roll down the first plane?
s
c) what is the acceleration along the second plane?
m/s2
d) what is the ball's speed 8.25 m along the second plane?
m/s

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
