Answer for Work and Energy Worksheet No.2

2.A tugboat pulls a ship with a constant force of 5000 N, causing the ship to move through 
a harbor. How much work does the tugboat do on the ship if each moves a distance of 3 
km?
  
W = F x D

     W = 5000N x 3km

     W = 5000N x 3000m

     W = 15000000 J
