A Man Of Mass 80kg Carry A Load Of Bricks Of 20kg Up A Vertical Of Length 6m Calculate The Workdone.
F*d:100
a man carry lot of brick of mass 80kg up to avertical lader of lenge 6m calculat the workdone of the man
F = M*g = (80+20)*9.8 =
Work = F*d.
Yes
To calculate the work done, we need to use the formula:
Work = Force * Distance
First, let's calculate the force exerted by the man while carrying the load up the vertical distance:
Force = Mass * Acceleration due to gravity
The mass of the man is given as 80 kg, and the load is 20 kg. Therefore, the total mass being lifted is (80 kg + 20 kg) which equals 100 kg. The acceleration due to gravity on Earth is approximately 9.8 m/s^2.
Force = 100 kg * 9.8 m/s^2
Force = 980 Newtons
Next, we calculate the distance the load is raised:
Distance = 6 meters
Now, we can substitute the values into the equation to calculate the work done:
Work = Force * Distance
Work = 980 N * 6 m
Work = 5880 Joules
Therefore, the work done in lifting the load of bricks up the vertical distance of 6 meters is 5880 Joules.
