Q1. What is the magnitude of an object's average velocity if an object moves from a point with coordinates x = 2.54 m, y = -3.56 m to a point with coordinates x = 7.85 m, y = -6.54 m in a time interval of 2.02 s?
Q2. The velocity of a particle moving along the x axis is given for t > 0 by vx = (32.0t - 2.00t3) m/s, where t is in s. What is the acceleration of the particle when (after t = 0) it achieves its maximum displacement in the positive x direction?
