During a workout, a football player pushes a blocking dummy a distance of 30 m. While pushing the dummy the same distance a seco nd time, what would the player need to change to be certain that power output increases?
1 answer:
Explanation:
Power = work / time
Work = force × distance
Therefore:
Power = force × distance / time
Since the distance is the same, he would have to either increase the force he exerts or decrease the time (increase his velocity) in order to increase the amount of work done.

Answer :
F = 1,875 N
Explanation :
force=
∆H = m∆V
where ∆H ----> change in momentum.
( final momentum - initial momentum )
and ∆V ----> change in velocity
( final velocity - initial velocity )
and m ----> is mass
then f =
= 1,875 N
