On Earth a robot is driving along a straight line in a testing facility. Researchers measure the motion of the robot as a function of time. Assume the robot starts at the origin in the middle of the room and moves in the positive direction initially. Make sure to show your work and/or explain your reasoning. The researchers determine the robot’s position as a function of time to be: A. What is the position of the robot 0.5 second after starting its motion? B. What is the velocity (including magnitude and direction) of the robot 0.5 second after starting its motion? C. What is the acceleration (including magnitude and direction) of the robot 0.5 second after starting its motion?
