A particle of mass 0.50 kg moves along the x-axis with a potential energy whose
dependence on x is shown below. (a) What is the force on the particle at x = 2.0, 5.0,
8.0, and 12 m? (b) If the total mechanical energy E of the particle is −6.0 J, what are
the minimum and maximum positions of the particle? (c) What are these positions if
E = 2.0J? (d) If E = 16J, what are the speeds of the particle at the positions listed in
part (a)?
