Question: A 900 g particle has velocity vx = -5.0 m/s at t=-2 s. Force Fx (t) = 50.et Newton is exerted on the particle

A 900 g particle has velocity vx = -5.0 m/s at t=-2

A 900 g particle has velocity vx = -5.0 m/s at t=-2 s. Force Fx (t) = 50.et Newton is exerted on the particle between t = -2 s and t = +2 s. This force increases from 0.0N at t = - 2 s to 20.0N at t = 0 s and then back to 0 N at t = 2 s. What is the particle's velocity at t = 2 s?
