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

Explanation :

During a workout, a football player pushes a blocking dummy a distance of 30 m.

Power is defined as the work done divided by time taken i.e.

Also,

s is the distance covered.

So, Power is directly proportional to the force and inversely proportional to the time taken.

To increase power output, the player would need to use a greater force and take less time.

Hence, the correct option is (b).
