The figure here shows a plot of potential energy U versus position x of a 0.852 kg particle that can travel only along an x axis. (Nonconservative forces are not involved.) Three values are UA = 15.0 J, UB = 35.0 J and UC = 45.0 J. The particle is released at x = 4.50 m with an initial speed of 7.89 m/s, headed in the negative x direction. (a) If the particle can reach x = 1.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (b) magnitude and (c) direction of the force on the particle as it begins to move to the left of x = 4.00 m ? Suppose, instead, the particle is headed in the positive x direction when it is released at x = 4.50 m at speed 7.89 m/s. (d) If the particle can reach x = 7.00 m, what is its speed there, and if it cannot, what is its turning point? What are the (e) magnitude and (f) direction of the force on the particle as it begins to move to the right of x = 5.00 m?

The figure here shows a plot of potential energy U versus position x of a 0.869 kg particle that can travel only along an x axis. (non-conservative forces are negligible) The three values of potential energy at the regions defined in the graph are UA = 15 J, UBB = 35 J. and UCC = 45 J. The particle is released at x = 4.5 m with an initial speed of 7.3 m/s. As the particle heads leftward along the x-axis. a) Determine if the particle can reach x = 1.0 m. If it can reach x = 1.0, determine the speed of the particle at x = 1.0 m. If it cannot reach x = 1.0 m, at what position, x, is its turning point? Determine the b) magnitude and direction of the force on the particle as it begins to move to the left of x = 4.0 m.

The figure shows a plot of potential energy U versus position x of a 0.230 kg particle that can travel only along an x axis under the influence of a conservative force. The graph has these values: UA = 9.00 J, UC = 20.0 J and UD = 24.0 J. The particle is released at the point where U forms a "potential hill" of "height" UB = 12.0 J, with kinetic energy 7.00 J. What is the speed of the particle at (a)x = 3.50 m and (b)x = 6.50 m ? What is the position of the turning point on (c) the right side and (d) the left side?

A plot of potential energy versus position is shown for a 0.27 kg particle that can move along an x axis as it is acted upon by a conservative force. In the graph, UA = 9.9 J, UC = 20 J and UD = 31 J (corresponding to x > 8 ). The particle is observed at the point where the potential energy U forms a curved "hill" to have kinetic energy of 4.22 J (At this point UB = 14 J). What is the difference in particle speed when it is located at x = 6.5 m compared to x = 3.5 m ? Assume mechanical energy is conserved. [Find the speed for x = 6.5 m and subtract the speed for x = 3.5 m] Δv = m/s What is the range of possible particle motion? [Find the turnaround location for the left and right side. The particle turns around when v = 0. Take the difference in these (right value minus left value) to get the range of the particle's motion] |Δx| = m
