Identical 45 μC charges are fixed on an x axis at x = ±3.1 m. A particle of charge q = −13 μC is then released from rest at a point on the positive part of the y axis. Due to the symmetry of the situation, the particle moves along the y axis and has kinetic energy 1.1 J as it passes through the point x = 0, y = 4.2 m. (a) What is the kinetic energy of the particle as it passes through the origin? (b) At what negative value of y will the particle momentarily stop? (a) Number Units (b) Number Units

In the first figure, a block of mass m lies on a horizontal frictionless surface and is attached to one end of a horizontal spring (spring constant k) whose other end is fixed. The block is initially at rest at the position where the spring is unstretched (x = 0) when a constant horizontal force in the positive direction of the x axis is applied to it. A plot of the resulting kinetic energy of the block versus its position x is shown in the second figure. The scale of the figure's vertical axis is set by Ks = 8.0 J. (a) What is the magnitude of F→? (b) What is the value of k? (a)

A plot of potential energy versus position is shown for a 0.203 kg particle that can move along an x-axis as it is acted upon by a conservative force. In the graph, UA = 8.6 J, UC = 23 J and UD = 30 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 4.98 J (At this point UB = 13 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
