The speed of propagation of waves shaking the boat is 1.5 meters per second.

The speed of propagation of waves shaking the boat is 1.5 meters per second. Determine the period of vibration of the boat if the wavelength is 6 meters.

Given:

u = 1.5 meters per second – the speed of propagation of waves shaking the boat;

l = 6 meters – wavelength.

It is required to determine T (second) – the period of vibration of the boat.

The boat vibrates under the action of waves on the surface of the water, so the period of the waves will be equal to the period of the boat. To find the period, you need to use the following formula:

u = l / T, hence:

T = l / u = 6 / 1.5 = 4 seconds.

Answer: the period of vibration of the boat is 4 seconds.
