Question

A woman pulls a 7.87 kg suitcase,
initially at rest, with a 29.2 N force
along the handle at 62.7° Friction
pulls back at 11.7 N, and the
suitcase moves 8.44 m. What is
the total work done?
(Unit = J)

Answer 1

Answer:

Effective Pulling Force = 29.2(cos 62.7°) = 13.393 N

Resistance to Pulling Force = 11.7 N

Net Force acting on suitcase = 13.393 - 11.7 = 1.693 N

Distance moved = 8.44 m

Net Work = 1.693(8.44) = 14.289 ≈ 14.3 J  ANS
