Dawn and Timothy are sailboating in Lake Obewon. Starting from rest near the shore, they accelerate with a uniform acceleration of 0.39 m/s/s. How far are they from the shore after 18 seconds? *

The value is  

Explanation:

From the question we are told that

   The uniform  acceleration is  

   The time considered is

Generally the from kinematic equation we have that

Given that the boat started from rest , the initial velocity is  u =  0  m/s  

So

=>      

b

explanation:

the skeletons of most mammals reach a certain size and then stop growing. however, many animals, including some mammals, keep growing throughout their lives. kangaroos, for example, just keep growing and growing until they die. also, the longer an animal lives the greater the chance it might catch some deadly disease.
