Question 23 Two frisky otters slide down frictionless hillsides of the same height but different slopes. The slope of the hill of otter 1 is 30°, while the slope of the hill of otter 2 is 60°. If both start from rest, which otter is moving faster when she reaches the bottom of her hill? O The otter that took the shorter time is moving faster. O Otter 2 is moving faster. O The heavier otter is moving faster, no matter which hill she used. O Otter 1 is moving faster. O Both otters have the same speed at the bottom.
