1a) W1=W2 = mgh
2a) P1 > P2 , mgh/25 >mgh/35
2) W=Fs=80•10 =800 J

The work done = potential energy gained = m g h.
That is the same for both since m, g and h are the same for both
The power is the work per unit time.
Power = m g h/t
so smaller t > bigger power

Calculate the work done when a person push acar from stationany position to a
distance of 50m appliny a. force of 200n.
