**Unformatted text preview: **11.0 m. This point may be found by interpolation or simply by using the work-kinetic-energy theorem: K f = K i + W = 0 11.9025 + (4) d = 0 d = 2.9756 2.98 (which when added to x = 8.00 [the point where F 3 begins to act] gives the correct result). This provides a turning point for the particles motion. 118. (a) At x = 5.00 m the potential energy is zero, and the kinetic energy is K = 1 2 mv 2 = 1 2 (2.00 kg)(3.45 m/s) 2 = 11.9 J....
