Question

During a workout, a football player pushes a blocking dummy a distance of 30 m. While pushing the dummy the same distance a second time, what would the player need to change to be certain that power output increases? The player would need to use a greater force and take more time. The player would need to use a greater force and take less time. The player would need to use a smaller force and take more time. The player would need to use a smaller force and take less time.

Answer 1

The player would need to use a greater force and more time.
Because realistically he would already be wore out from the first time. Therefore exerting more force would still wear you out and thus taking more time. 

Take this from a former linebacker :)

Answer 2

The above answer is incorrect.  The correct answer is The player would need to use a greater force and take less time.  I am positive because I just took the test.
