we neglect the air resistance acting on the balloon of a volley-ball .A player hits the baloon that is situated at point A and throws it with velocity v0 of magnitude 15m/s making an angle 20(degree) with horizontal. The point A is at a height of H=3m from the ground the net is at D=12m from the player ,the height of the net is H=2.4m. 1)show that the service succeeds 2)A player situated at 2m from the net wants to intercept the balloon. at which height H should he put his hands in the plane of the trajectory of the balloon

The particle in a two-dimensional well is a useful model for the motion of electrons around the indole ring (3), the conjugated cycle found in the side chain of tryptophan. we may regard indole as a rectangle with sides of length 280 pm and 450 pm, with 10 electrons in the conjugated p system. as in case study 9.1, we assume that in the ground state of the molecule each quantized level is occupied by two electrons. (a) calculate the energy of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels. 9.27 electrons around the porphine ring (4), the conjugated macrocycle that forms the structural basis of the heme group and the chlorophylls. we may treat the group as a circular ring of radius 440 pm, with 20 electrons in the conjugated system moving along the perimeter of the ring. as in exercise 9.26, assume that in the ground state of the molecule quantized each level is occupied by two electrons. (a) calculate the energy and angular momentum of an electron in the highest occupied level. (b) calculate the frequency of radiation that can induce a transition between the highest occupied and lowest unoccupied levels.
