1. While traveling along a highway a driver slows from 24 m/s to 15 m/s in 12 seconds. What is theautomobile's acceleration? (Remember that a negative value indicates a slowing down.)

Respuesta :

Given data

*The initial speed of the driver is u = 24 m/s

*The final speed of the driver is v = 15 m/s

*The given time is t = 12 s

The formula for the automobile's acceleration is given as

[tex]a=\frac{v-u}{t}[/tex]

Substitute the values in the above expression as

[tex]\begin{gathered} a=\frac{15-24}{12} \\ =-0.75m/s^2 \end{gathered}[/tex]
