The acceleration of a particle is given by a(t)=-2.03 m/s + (3.04 m/s)t. Find the initial velocity voz such that the particle will have the same x-coordinate at time t = 3.93 s as it had at t = 0. Express your answer in meters per second. What will be the velocity at time t = 3.93 s? Express your answer in meters per second.
