3. x B A particle moves in 1D with a potential energy function U(x) = -, where A = 10.0J cm and B = 5.0 J. cm. a) Draw a graph of this potential energy function between x = 0 m and x = 20 cm. b) Calculate the x-position of the minimum potential energy. c) Calculate the minimum potential energy or the "binding energy" of this potential. d) Consider a particle moving in this potential with total energy E = -0.22 J. Calculate the x- position of the two turning points for this energy value.
