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.
Answer:
Explanation: So then you can make a calculation. It is pretty obvious really.
