How can you change your velocity

You could change your velocity by altering both your speed and direction.

For example, if you are running north at 10 miles per hour, and turn into a street going east, then slow down to 5 miles per hour, you would have changed your velocity.

n = 7.5 times/minute

Explanation:

Given that,

Wavelength of the ocean wave,

The speed of the ocean wave, v = 5 m/s

To find,

Number of times a minute does a boat bob up and down on ocean waves.

Solution,

The relation between the speed of wave, wavelength and frequency is given by :

f = 0.125 Hz

The number of times per minute the bob moves up and down is given by :

n = 7.5 times/minute

So, its will move up and down in 7.5 times/minute. Therefore, this is the required solution.
