A boy weighing 40 kg carries a box weighing 20 kg to the top of a building 15 m high in 25 seconds. Calculate the power. (g=10 m/s square)
Answers
Work = Potential Energy
Mass = 40+20 = 60 kg
Height = 15 m
Time = 25 sec
Work = 60*15*10
Time = 25
=> 60*15*10/25 = 360 Watt
Solution :
Given Data :
Total mass = 60
{Mass of Box = 40
Mass of Boy = 20}
Time = 25 Seconds
g = 10m/s
We need to find the power
p = (f × s) / t
But before this we need to find the force.
f = m × g
f = 60 × 10
f = 600
Now, apply the value of force into equation of power
p = (f × s) / t
p = (600 × 15)/ 25
p = 9000/ 25
p = 360 w
