Question

A tugboat pulls a ship with a constant net horizontal force of 4.71 × 103 N and causes the ship to move through a harbor. How much work does the tugboat do on the ship if each moves a distance of 4.57 km ?

Answer 1

Answer:

21.53 x 10^{6} N

Explanation:

force (F) = 4.71 x 10^{3} N

distance (s) = 4.57 km = 4570 m

how much work is done.

work = force x distance

work = 4.71 x 10^{3} x 4570 = 21.53 x 10^{6} N
