Work done : 19.5 J

Further explanation

Given

F = 15 N

d = 1.3 m

m = 3 kg

Required

Work done

Solution

Work is the product of force with the displacement of objects.  

Can be formulated  

W = F x d  

W = Work, J, Nm  

F = Force, N  

d = distance, m  

Input the value :

W = 15 N x 1.3 m

W = 19.5 J

the mass has no effect on this problem
