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.

Explanation:

Power is defined as work done per unit time. Work is force times distance. If distance is constant, increasing force increases work. And to increase power, with work increased, time should be decreased.

Answer:

The player would need to use a greater force and take less time.
