To calculate the work done by the man in carrying the load of bricks up a vertical distance of 6 meters, we need to use the formula:
Work = Force x Distance
The force required to do the work against gravity can be calculated using the formula:
Force = Mass x Gravity
Here, the mass of the man is 80 kg and the mass of the bricks is 20 kg. The acceleration due to gravity can be taken as 9.8 m/s^2.
First, let's calculate the force:
Force = (80 kg + 20 kg) x 9.8 m/s^2
= 100 kg x 9.8 m/s^2
= 980 N
Now, we can calculate the work done:
Work = Force x Distance
= 980 N x 6 m
= 5880 Joules
Therefore, the work done by the man in carrying the load of bricks up a vertical distance of 6 meters is 5880 Joules.
