1) A car starts from 2.00 m/s and accelerates at 4.00 m/s² for 6.00 s, it then coasts for 5.00 s. How far has it traveled, in meters?

2) A car starts from 2.00 m/s and accelerates at 4.00 m/s² for 6.0 s, it coasts for 5.00 s, and then slows down at a rate of 2.00 m/s² to a stop. How far has it traveled, in meters?

3) Figure below is a velocity-versus-time graph for a moving object. The object starts at position x = 0. What is the acceleration at t = 4.0 s, in m/s²?
