The equation for the motion of an object with constant acceleration is d=vt+0.5at? where d is distance traveled in ft, v is starting velocity in ft/s, a is acceleration in ft/s2, and t is time in seconds. A racecar begins with a velocity of 200 ft/s and accelerates at 105 ft/s2. Write an expression for the distance the car travels after t seconds. What is the GCF of the expression? ​
