A 500 g particle has velocity vx = -5.0 m/s at t = -2 s.
Chapter 11, Problem 11.97(choose chapter or problem)
A 500 g particle has velocity vx = -5.0 m/s at t = -2 s. Force Fx = 14 - t 2 2 N, where t is in s, is exerted on the particle between t = -2 s and t = 2 s. This force increases from 0 N at t = -2 s to 4 N at t = 0 s and then back to 0 N at t = 2 s. What is the particles velocity at t = 2 s?
