Two ships of equal mass are 109 m apart. What is the acceleration of either ship due to the gravitational attraction of the other? Treat the ships as particles and assume each has a mass of 39,000 metric tons. (Give the magnitude of your answer in m/s2.)

The acceleration is  

Explanation:

From the question we are told that

      The  distance of separation of the ship is  

       The mass of each ship is  

The gravitational force of attraction exerted on each other is mathematically represented as

Where G is the gravitational  constant with value

substituting values

This force can also be mathematically represented as

=>  

substituting values

the part of the wave he is travelling on is the crest
