Answer:
The work done is 2.94 Nm.
Explanation:
First, you have to find the force of a brick layer using the formula, Force = mass×gravity :
[tex]f = m \times g[/tex]
[tex]let \: m = 10,g = 9.8[/tex]
[tex]f = 10 \times 9.8[/tex]
[tex]f = 98N[/tex]
Given that the force of a brick layer is 98N. Next, you have to apply work done formula, Work done = force×distance :
[tex]w.d = f \times d[/tex]
[tex]let \: f = 98,d = 0.03m[/tex]
[tex]w.d = 98 \times 0.03[/tex]
[tex]w.d = 2.94Nm[/tex]
