Problems 61 through 80 are worth 4 points each: a particle moves along the x-axis. The particle has an x-component of the acceleration given by ax = (3. 00 m/s4)t2 where t is the time in seconds. The initial x-component of the velocity of the particle at time t = 0. 00 s is 9. 00 m/s. The x-component of the velocity of the particle at time t = 2. 00 s is vx = ____ m/s: 0. 4, 1. 0, 0. 6, 0. 8.
