How much work would a child do while puling a 12-kg wagon a distance of 3m with a 22 N force directed 30 degrees with respect to the horizontal? (A) 82J (B) 52J (C) 109J (D) 95J

Respuesta :

Answer:

The work done will be 57.15 J

Explanation:

Given that,

Mass = 12 kg

Distance = 3 m

Force = 22 N

Angle = 30°

We need to calculate the work done  

The work done is defined as,

[tex]W = Fd\cos\theta[/tex]

Where, F = force

d = displacement

Put the value into the formula

[tex]W=22\times3\times\cos30^{\circ}[/tex]

[tex]W=22\times3\times\dfrac{\sqrt{3}}{2}[/tex]

[tex]W = 57.15\ J[/tex]

Hence, The work done will be 57.15 J
