Answer:

When a ball accelerates toward bottom it experiences both rolling friction and air resistance.

Explanation:

  • When the ball rolls from the hill the gravitational force of attraction comes in action and accelerates the ball toward the bottom of the hill.
  • This motion of ball is the rotational motion,  rolling friction acts on it due to rotational motion.
  • As the velocity of the ball increases air resistance also starts to have significant effect on its motion.
  • These two forces try to oppose the motion of the ball.
