Question

Calculate the workdone by a bricklayer who lifted cement block of mass 10kg from the floor to the height of 3cm g=9.8m​

Answer 1

The work done is 2.94 Nm.

Step-by-step explanation:

First, you have to find the force of a brick layer using the formula, Force = mass×gravity :

`f = m * g`

`let \: m = 10,g = 9.8`

`f = 10 * 9.8`

`f = 98N`

Given that the force of a brick layer is 98N. Next, you have to apply work done formula, Work done = force×distance :

`w.d = f * d`

`let \: f = 98,d = 0.03m`

`w.d = 98 * 0.03`

`w.d = 2.94Nm`
