A student is given a problem in which a car speeds up from rest to 30 m/s in 6 seconds. The student states that the acceleration of the car is 30 m/s/s. Which is the best analysis of this answer? A) The student is correct. B) It is the velocity and not the acceleration which is 30m/s/s. C) The student forgot to divide by the time which would yield 5 m/s/s. D) The student forgot to multiply by the time which would yield 180 m/s/s.
