Lisa wanted to find out if changing the height of an object would affect the distance it traveled when released. She rolled a golf ball down a ramp at heights of 100 cm, 75 cm, 50 cm, and then 25 cm. She repeated her experiment three times. Lisa should expect the golf ball to roll the farthest when dropped from this height.
What is 100 cm?
