use formula power =mgh/t...200×10×9.8/4.9. =4000w and change it in h.p by dividing it by746

Power=work/time
according to work energy theorem ..the amou t of energy spent is equal to amount of work done

Answer:
4000 w i.e 5.37 horse power
Explanation:
since power = work done / time
therefore , power = mgh / t
power = 200×9.8×10 / 4.9
therefore power = 4000 watts
to convert it into horse power, divide it by 746
4000 / 746 = 5.37 hp ( approximate value)
