A particle with mass of 2 kg enters this region of space. When it is at x = 0. it is U\") moving to the right with a kinetic energy of 4 'l Joule. What is the maximum speed the 3 particle will have as it travels through this region? 2 1 A. 0.5 m/s 0 B. 0.7 m/s (2. 1.0 m/s '1 D. 1.7 m/s -2 E. 2.0 m/s Potential energy le] for a conservative force. X is in meters, U is in Joules
