D Question 16 1 pts An accelerometer is a device that records a vehicle's acceleration at each moment. Suppose a(t) gives the vehicle's acceleration, in (ft/sec)/sec, at t seconds after it begins from a stationary position. Which of the following expressions gives the number of feet the vehicle has moved from its starting position by x seconds after starting? Note that velocity is the rate of change of position, with respect to time and acceleration is the rate of change of velocity with respect to time. .
