Speedy sue, driving at 30.0 m/s, enters a one lane tunnel. she then observes a slow moving van 155 m ahead traveling at 5.00 m/s. sue applies her brakes, but can accelerate only at -2.00 m/s2 because the road is wet. will there be a collision? state how you decide. if yes, determine how far into the tunnel and what time the collision occurs. if no, determine the distance of closest approach between sue’s car and the van.

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?
