Calculate the work done by a Mason in lifting 5.5kg ston through a night of 2m
The work done by a Mason in lifting a stone can be calculated using the formula:
Work = Force x Distance x cos(angle)
In this case, the force is the weight of the stone, which is 5.5kg multiplied by the acceleration due to gravity, which is 9.81 m/s^2. So the force exerted by the Mason is:
Force = 5.5kg x 9.81 m/s^2 = 53.955 N
The distance through which the stone is lifted is 2m.
Now, let us calculate the work done by the Mason:
Work = 53.955 N x 2m x cos(0 degrees) = 107.91 J
Therefore, the work done by the Mason in lifting the stone through a height of 2m is 107.91 Joules.
