Final answer:
The work done by a bricklayer lifting a cement block of mass 10 kg to a height of 0.03 m is 2.94 J.
Step-by-step explanation:
The work done by a bricklayer lifting a cement block can be calculated using the formula:
Work (W) = Force (F) x Distance (d)
The force required to lift the cement block can be calculated using the formula:
Force (F) = Mass (m) x Acceleration due to gravity (g)
Given that the mass of the cement block is 10 kg and the height lifted is 0.03 m:
Force (F) = 10 kg x 9.8 m/s^2 = 98 N
Therefore, the work done by the bricklayer is:
Work (W) = 98 N x 0.03 m = 2.94 J
