A body of mass 2 kg initially at rest moves under the action of an applied horizontal force of 7N on a table with coefficient of kinetic friction =0.1 . Calculate the (a) work done by applied force in 10s. (b) work done by friction in 10s. (c ) work done by the net force on the body in 10s. (d) change in K.E. of body in 10s, and interpret your result.

At a temperature of 0 K , the total energy of a gaseous diatomic molecule AB is approximately given by: E=E_(o)+E_(vib) where E_(o) is the electronic energy of the ground state, and E_(vib) is the vibrational energy. Allowed values of the vibrational energies are given by the expression: E_(vid)=(v-1/2)epsilon " " v=0, 1, 2, ....... " " epsilon=h/(2pi)sqrt(k/mu) " " mu(AB)=(m_(A)m_(B))/(m_(A)+m_(B)) where h is the planck's constant, is the vibration quantum number, k is the force constant, and is the reduced mass of the molecule. At 0K , it may be safely assumed that is zero, and E_(o) and k are independent of isotopic substitution in the molecule. Deuterium, D, is an isotope of hydrogen atom with mass number 2 . For the H_(2) molecule, k is 575.11 N m^(-1) , and the isotopic molar masses of H and D are 1.0078 and 2.0141 g mol^(-1) , respectively. At a temperature of 0K : epsilon_(H_(2))=1.1546 epsilon_(HD) and epsilon_(D_(2))=0.8167 epsilon_(HD) A molecule H_(2) in the ground state dissociates into its atoms after absorbing a photon of wavelength 77.0 nm . ul("Determine") all possibilities for the electronic states of hydrogen atoms produced. For each case calculate the total kinetic energy, KE, in eV of the disociated hydrogen atoms.
