2. A weather probe is launched in the air. The probe's height, in feet, afterxseconds is given by the function Mac) 2 169r'2 + 640x + 16404 NOTE: The "rate of change\" of the position of an object is called \"velocity\". The absolute value of an object's velocity is called \"speed\" (the +/ sign for the velocity tells you the direction the object is moving.) a. What is the probes average velocity over the time interval [0,2] seconds? What is the average speed? Is the probe going up or down? @4510) b. What is the probes average velocity over the time interval [20,22] seconds? What is the average speed? Is the probe going up or down
