Question 2: A snowboarder starts from rest at the top of a double black diamond hill. As she rides down the slope, GPS coordinates are used to determine her displacement as a function of time given by the image below, where x and t are expressed in feet and seconds, respectively. Determine the displacement, average velocity, average speed and average acceleration for the time period from t=2 seconds to t=7 seconds. Write your answer in the format (d = ft; v_avg = _ ft/s; V_sp = _ ft/s; a_av = ft/s^2) * %3D x = 0.5t³ + t² + 2t
