Question

calculate the power output of a machine that lifts a 50kg crate through a height of 20.0m in one minute ​

Answer 1

Answer:

power= work done/ time

power=mgh/time

mass(m) =50kg

acelleration due to gravity (g)= 10g/m^2

height(h) =20.0m

time = 1min

Explanation:

power =50×10×20 /1

power = 10,000watts

power =10 ×10^3kw

p =10 Kilowatt's
