1. The problem statement, all variables and given/known data http://img265.imageshack.us/img265/4572/graphrj8.jpg [Broken] (The particle starts from rest at the origin.) 1: What is the velocity at t = 5s? 2: What is the position at t = 5s? 3. The attempt at a solution I'm thinking -2 m/s velocity and -8 m position at t = 5s, but would like someone to double-check my understanding of reading velocity and position from this graph. The negative acceleration at origin combined with that instantaneous change at t = 1 have me a bit unsure of myself.
