Answer:

W=2.60 J

Explanation:

Given that

m = 41 kg

d= 10.6 mm

Coefficient of friction = 0.6

Friction force ,Fr=μ m g

Fr= 0.6 x 41 x 10 N               ( take g= 10 m/s²)

Fr= 246 N

We know that work done by a force given as

W = F . d

Now by putting the values

W= 246 x 10.6 x 10 ⁻³  J

W=2.60 J

Therefore the work done by movers in the horizontal direction will be 2.60 J.The mover does the work against the friction force.
