  5. Forces and Motion for $100 5. Jenny has two identical marbles. She rolls one marble across a concrete surface with a force of 2N. At the same time, she rolls the other marble across an icy surface with the same force. There is significantly greater frictional force between the first marble and the concrete surface than between the second marble and the icy surface. This means that… The first marble will roll a longer distance than the second marble. The first marble will slow down and stop before the second marble. The second marble will slow down and stop before the first marble. The second marble will roll exactly the same distance as the first marble.

  6. b. The first marble will slow down and stop before the second marble. Back toGame
