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

Answer:

d = 108 m

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

$a=\dfrac{F}{m}\\\\a=\dfrac{900\ N}{600\ kg}\\\\a=1.5\ m/s^2$

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

$d=ut+\dfrac{1}{2}at^2\\\\d=0+\dfrac{1}{2}\times 1.5\times (12)^2\\\\d=108\ m$

So, the boat will travel 108 m.
