Answer:

The work done will be 57.15 J

Step-by-step 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,

$W = Fd\cos\theta$

Where, F = force

d = displacement

Put the value into the formula

$W=22*3*\cos30^(\circ)$

W=22*3*(√(3))/(2)

$W = 57.15\ J$

Hence, The work done will be 57.15 J
