Identify the description of motion that’s consistent with constant acceleration. Neither the ball nor the car could have had constant acceleration. A ball rolling up an inclined plank slows down, stops, then rolls back down to the bottom of the plank, speeding up as it goes. Both the ball and the car could have had constant acceleration. Starting from rest, a car speeds up at a steady rate for a few seconds, then slows down at a steady rate for a few seconds, finally stopping again.
