A sailboat accelerates uniformly from
5.5 m/s to 9.0 m/s over a distance of 32 m.
At what rate is the boat accelerating?


Sagot :

To find the rate of acceleration, we can use the kinematic equation that relates initial velocity u, final velocity v, acceleration a, and distance s:

[tex]v^2=u^2+2as[/tex]

Given:

- Initial velocity, u = 5.5 m/s

- Final velocity, v = 9.0 m/s

- Distance, s = 32 m

We need to solve for acceleration a. Rearranging the equation for a:

[tex]a=(v^2-u^2)/2s[/tex]

Substituting the given values:

[tex]\[ a = \frac{(9.0 \, \text{m/s})^2 - (5.5 \, \text{m/s})^2}{2 \times 32 \, \text{m}} \][/tex]

Let's calculate it:

[tex]\[ a = \frac{81 - 30.25}{64} \]\[ a = \frac{50.75}{64} \]\[ a \approx 0.793 \, \text{m/s}^2 \][/tex]

So, the rate at which the boat is accelerating is approximately [tex]\( 0.793 \, \text{m/s}^2 \).[/tex]
