Answer 2

Hey mate,
You posted an incomplete question.

◆ Complete question is-
0.60 kg book slides on a horizontal table. The kinetic friction force on the book has magnitude 1.3 N. How much work is done on the book by friction during a displacement of 3.3 m ?

◆ Answer-
Work done = 4.95 J

◆ Explanation-
# Given-
m = 0.6 kg
F = 1.5 N
s = 3.3 m

# Solution-
Work done by kinetic friction force is -
W = F.s
W = 1.5 × 3.3
W = 4.95 J

Therefore, work done in moving book is 4.95 J.

Hope it helps...
