How much power is neccessary to raise a drum of mass 150kg through a height of 20m in one minute?

Answers

Answered by RisingFlame

m=150 kg h=20 m g=10m/s
time =1 minute=60 seconds
power =workdone /time
= (mgh)/time =(150×9.8×20)/60=490 W

AFridiiiKhaaannn: and how 0.657hp?

RisingFlame: see 1 HP (horse power )=746 W so 490 W =490/746 hp=0.657 hp

AFridiiiKhaaannn: okay so any similar question I can denominator 746 watt and x watt in nuemarator

RisingFlame: yes bro

AFridiiiKhaaannn: Thanks

RisingFlame: hp is a bigger unit

RisingFlame: used in engineering for bigger calculations

AFridiiiKhaaannn: i got you

RisingFlame: well bye then

AFridiiiKhaaannn: see you again

ANSWER
..........

M = 150 KG
H = 20 M
G = 10 M / S
T = 60 SECOND

.........

POWER = WORK DONE
__________
time

mgh / time
= (150 × 9.8 ×20 ) / 60
= 490 watt

AFridiiiKhaaannn: got you !
