Question

How far will a 600kg boat travel in 12 s if there is a constant 900N force on it and it starts from rest?

Answer 1

d = 108 m

Step-by-step explanation:

Given that,

Initial speed, u = 0

Mass of the boat, m = 600 kg

Time, t = 12 s

Force on boat, F = 900 N

Firstly, we can find the acceleration of the boat using formula, F = ma

`a=(F)/(m)\\\\a=(900\ N)/(600\ kg)\\\\a=1.5\ m/s^2`

Let it will travel d distance. Using second equation of motion to find it as follows :

`d=ut+(1)/(2)at^2\\\\d=0+(1)/(2)* 1.5* (12)^2\\\\d=108\ m`

So, the boat will travel 108 m.
