Two equal mass marbles are at the top of a ramp. One marble falls to the ground off the back while the other rolls down the ramp. What is true about the marbles when they reach the ground?

• The marble that rolled down the ramp is moving faster than the marble that fell.

• The marble that fell down the back of the ramp is moving faster than the marble that rolled.

• The marble that rolled down the ramp is not moving when it reaches the ground.

• The two marbles are moving with the same speed.
