Suppose you have made the following hypothesis: the greater the height from which you drop a ball, the faster the ball will be traveling when it hits the ground because gravity has more time to speed it up.

what prediction could you make based on this hypothesis?

a. two identical balls dropped from a height of 5 m will hit the ground with different speeds.

b. two identical balls dropped from a height of 10 m will hit the ground with different speeds.

c. a ball dropped from a height of 10 m will hit the ground at a higher speed than an identical ball dropped from a height of 5 m.

d. a ball dropped from a height of 5 m will hit the ground at a higher speed than an identical ball dropped from a height of 10 m.
