Expert Solution

Step 1

Here work done by the applied force is

$W = F o r c e a p p l i e d \times d i s p l a c e m e n t = 2 \times 5 = 10 J o u l e$

Work done by the Friction force is

$W_{f} = F r i c t i o n f o r c e \times d i s p l a c e m e n t = 10 \times 5 = 50 J o u l e$

Change in Kinetic energy is

$K = 59 J o u l e$
