Question

A tugboat pulls a ship with a constant net horizontal force of 5.00 x 10 to the 3 power n and causes the ships to move through a harbor how much work is done on the ship if it moves distance of 3.00 kilometers

Answer 1

Work is force times distance. So here we have
W=(5000N)x(3000m)=1.5x10^7J
Or 15MJ (megajoules)
