a man carries a load of 50 kg to a height of 15 m in 5 minutes. calculate the work load?
The work is
W = M g H =
(50 kg)*(9.8 m/s^2)*(15 m) = 7350 Joules
Divide that by 300 seconds for the average power in Watts.
I have never heard of power referred to as "work load", but assume that is what they mean.
To calculate the work done in carrying a load, we can use the formula:
Work = Force x Distance
In this case, the force is equal to the weight of the load. The weight of the load can be calculated using the formula:
Weight = mass x gravitational acceleration
Where the mass is given as 50 kg and the gravitational acceleration is typically around 9.8 m/s^2 (approximately).
Therefore, weight = 50 kg x 9.8 m/s^2 = 490 N
The distance is given as 15 m.
Now, we can calculate the work done:
Work = 490 N x 15 m = 7350 Joules
So, the work done in carrying the load to a height of 15 m is 7350 Joules.
