Answer 1

Answer:

Given :

A boat accelerates at a constant rate of 3 m/s² for 8 seconds .

To Find :

Distance travelled by the boat during the given time .

Solution :

$\longmapsto\tt{Acceleration\:(a)=3m/{s}^{2}}$

$\longmapsto\tt{Initial\:Velocity\:(u)=0\:m/s}$

$\longmapsto\tt{Time\:Taken\:(t)=8\:sec}$

Using Equation :

$\longmapsto\tt\boxed{s=ut+\dfrac{1}{2}\:a{t}^{2}}$

Putting Values :

$\longmapsto\tt{s=0\times{8}+\dfrac{1}{2}\times{3}\times{{(8)}}^{2}}$

$\longmapsto\tt{s=0+\dfrac{1}{{\cancel{2}}}\times{3}\times{{\cancel{64}}}}$

$\longmapsto\tt{s=3\times{32}}$

$\longmapsto\tt\bf{s=96\:m}$

So , The distance travelled by the motor boat is 96 m .

Three Equations Of Motion :

v = u + at

s = ut + 1/2 at²

v² - u² = 2as

Here :

v = Final Velocity

u = Initial Velocity

t = Time Taken

a = Acceleration

s = Distance Travelled
