A train moving in a straight line with an initial velocity of 0.50 m/s accelerates at 2.0 m/s^2 for 2.0 seconds, coasts with zero acceleration for 3.0 seconds, and then accelerates at -1.5 m/s^2 for 1.0 seconds. (a) What is the final velocity of the train? (b) What is the average acceleration of the train? Thank you!!!!1
