please explain your answer and draw graph. Also label the answers thoroughly. Answer both for thumbs up:)) m2 6 Fig awre . 2. The magnitude of the force of attraction between the positively charged proton and the negatively charged electron in a Hydrogen aton is given by f(r) = ke2/r2 where e is the charge on the proton, k is Coulomb's constant, and r is the distance between the proton and the electron. Assume that the protorn can't move. The...
Question 2 (a) Using the component method, in adding the two vectors: 14 N in the x direction and 13 N at 45° elevation, (b) : (i) Calculate the momentum of a 8000 kg locomotive travelling at 12 m/s. (ii) This locomotive collides with a stationary carriage of mass 2500 kg and they shunt (stick together). What would be the velocity of the combination, assuming there is negligible friction. (iii) Would kinetic energy be conserved in this collision? Show...
