Soal OFI 1:1. A ball of mass M = 0,2 kg rests on a vertical column, height h = 5 m. Abullet, mass m = 0,01 kg, traveling at v 0 = 500 m/s, passes horizontallythrough the center of the ball. The ball reaches the ground at a distance ofs = 20 m. Where does the bullet reach ground? What part of the kineticenergy of the bullet was transferred as heat to the bullet?Soal OFI XI1. A space ship of mass m = 12 ton is revolving on a circular orbit about themoon in height h = 100m. In order to reach the surface of the moon its jetengine is switched on at point X for a short time. The velocity of the hot gasesissueing from the nozzles u = 10.000 m/s relative to the space ship. The radiusof the moon R = 1700 km, the acceleration of free fall on its surface g = 1,7m/s 2 . The space ship can reach the moon by two different methods (seefigure): a) arriving on the moon in point A, opposite to point X; b) touchingthe moon surface tangentially at point B after having given a momentumdirected toward the center of the moon at point X. Calculate the quantity offuel necessay in each case.BAXAX13
SOAL OFI XXVIINuclear Masses and StabilityAll energies in this question are expressed in MeV - millions of electron volts.One MeV = 1.6 10 -13 J, but it is not necessary to know this to solve the problem.The mass M of an atomic nucleus with Z protons and N neutrons (i.e. the massnumberA = N + Z) is the sum of masses of the free constituent nucleons (protons andneutrons) minus the binding energy B/c 2 .The graph shown below plots the maximum value of B/A for a given value of A, vs.A. The greater the value of B/A, in general, the more stable is the nucleus.Binding Energy per Nucleon(a) Above a certain mass number A , nuclei have binding energies which arealways small enough to allow the emission of alpha-particles (A=4). Use a linearapproximation to this curve above A = 100 to estimate A . (3 marks)For this model, assume the following:14
