Question

Calculate the power of an engine which is lifting a mass of 150kg
through 5m in 2 minutes.

Answer 1

Answer:

p=w/t =mgh/t

p=150x5/120

=6.25w

Explanation:

the power of an engine is 6.25w

Answer 2

Answer:

here is your answer

Explanation:

P=Force velocity

Force= Weight = Mass Acceleration due to gravity.

g is approximately 10 m/s^2 ~ 9.81 m/s^2

P = 150kg10m/s^2  velocity

Lets say you want to lift it at 2 meters/second,

P=F V

P= 1500N 2m/s

P= 3000W = 3kW
