In parts b and c you saw that, according to bohr's postulate, the electron radius r and the electron velocity v only have certain allowable values. plug the values obtained for these two quantities into the energy statement given below (e=) to arrive at a new statement for the allowed energy levels in the bohr atom. express answer in terms of e, m, n, h, \epsilon _{0} . equations: v=nh/2mr\pir=n^{2}h^{2}\epsilon _{0}/m\pi e^{2}e=\frac{1}{2}mv^{2}-(e^{2}/4\p i r\epsilon _{0})

Two cannon balls weighing 18 kg and 24 kg are chained together and fired horizontally with a velocity of 165 m/s from the top of a 21-m wall. the chain breaks during the flight of the cannonballs and the 18-kg cannonball strikes the ground at t = 1.5 s, at a distance of 240 m from the foot of the wall, and 7 m to the right of the line of fire. determine the position of the other cannonball at that instant. neglect the resistance of the air.
