What scenario involves kinetic energy transform into potential energy

The object which is projected upwards. The kinetic energy imparted as its launch is converted into potential energy as an object Rises until, at the peak of its motion, all the kinetic energy has been converted to additional potential energy

The wavelength of the water is

Explanation:

From the question awe are told that

               The distance between the two boats are 46 m

  Now we are told that a the time the Jenny's boat is at a crest,Melissa's boat is at its lowest point, and there are 4 additional crests between them which can be mathematically represented as

                        Number of wavelength = 4 + 0.5(this accounts for the difference in position crest and lowest point)

                                                             = 4.5

Now the wavelength of the water is
