A car travelling at 15 m/s comes to rest in a distance of 14 m when the brakes are applied.
Calculate the deceleration of the car.

Respuesta :

Answer:

-8.04 m/s2

Explanation:

To find the answer to this, you have to use the 4th kinematic equation:

[tex]v^{2} = v^{2}_{0} + 2ax[/tex]

You plug into the equation to get:

[tex]0 = 15^{2} + 2a(14)[/tex]

solve for a to get

-8.04 m/s2
