You are pushing a wooden crate across the floor at a constant speed. You decide to change the orientation of crate such that area of contanct with floor becomes half. In the new orientation, to push the same crate across the same floor with the same constant speed, the force that you apply must be about__________ as the force required before you changed the crate's orientation.

A

4 times as great

B

2 times as great

C

equally greate

D

1/2 as great
