Question

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? *

Answer 1

The value is
`s =63.18 \ m`

Step-by-step explanation:

From the question we are told that

The uniform acceleration is
`a = 0.39 \ m/s^2`

The time considered is
`t = 18 \ seconds`

Generally the from kinematic equation we have that

`s = ut + (1)/(2) at^2`

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

So

`s = 0 * 18 + (1)/(2) *0.39 * 18^2`

=>
`s =63.18 \ m`
