First we need to calculate the work done in lifting the crate:
Work = force x distance
Force = mass x acceleration due to gravity = 50kg x 9.8 m/s^2 = 490 N
Distance = height = 20m
Work = 490 N x 20m = 9800 Joules
Power is defined as the rate at which work is done, so we can calculate the power using the formula:
Power = Work / time
Given that the time taken to lift the crate is 1 minute = 60 seconds
Power = 9800 Joules / 60 seconds = 163.33 watts
Therefore, the power output to lift a 50kg crate through a height of 20m in 1 minute is 163.33 watts.
Compute the power output in watts 50kg crate through a height of 20m in 1 minute?
