1. A train begins at some velocity v0 and accelerates at a constant rate of 2.0m/s2. At the end of its motion, it has traveled 580m and its final velocity is 55m/s. What is v0? How long did it take for the train to accelerate from v0 to 55m/s?

2. Based on the velocity vs. time graph of a particle shown, determine the particle’s acceleration at t=3s and how far it travels between t=0s and t=0.5s
