Question
1. The figure below shows a plot of potential energy U versus position x of a 0.100 kg particle that can travel only along an x axis under the influence of a conservative force. There are no other forces acting upon the particle. The graph has these values: Ua = 9.00 J, UB = 12.00 J. Uc= 20.00 J. and Up = 24.00 J. The kinetic energy of the particle at x-5.00 m is KB-4.00 J d) Find the magnitude and the direction of the force on the particle in the region between x = 1.0 m and x = 3.0 m. 1 245 67 89 x (m)Explanation / Answer
force = - slope of the graph
F = -dU/dx
F = -((Uc - UA)/(3-)
F = -(20 - 9)/2
F = -11/2 = -5.5 N
magnitude 5.5 N
direction = - x axis
