... can use Equation 10.6 , with force F = T, to find that the tension does work: W = Td cos θ = (20 N)(100 m)cos 45° = 1400 J The tension is needed to do work on the suitcase even though the suitcase is traveling at a constant speed to overcome friction. So it makes sense that the work is positive. The ...
