A boat moving 18ft/sec slows to a stop in 9 seconds. What is it’s acceleration?

Sagot :

Given:

The initial velocity of the boat is,

[tex]u=18\text{ ft/s}[/tex]

The final velocity of the boat is,

[tex]v=0[/tex]

The boat stops after,

[tex]t=9\text{ s}[/tex]

If the acceleration is a, we can write,

[tex]v=u+at[/tex]

Substituting the values we get,

[tex]\begin{gathered} 0=18+a\times9 \\ a=-\frac{18}{9} \\ a=-2ft/s^2 \end{gathered}[/tex]

Hence the acceleration is -2 ft/s^2.
