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: x = 0.25³ +2+2t, where x and t are expresse in feet and seconds, respectively. x is measured along the surface of the hill. Determine the position, velocity, and acceleration of the boarder when t = 9.0 seconds. The position, velocity, and acceleration of the boarder are ft/s, and ft/s², respectively when t = 9.0 seconds.
