A car is traveling at 19.44m/s. The driver speeds up to 22m/s over a period of 0.65 seconds to pass a car in front of her. What is the acceleration of the car?

Respuesta :

Given data

*The given initial speed of the car is u = 19.44 m/s

*The given final speed of the car is v = 22 m/s

*The given time is t = 0.65 s

The formula for the acceleration of the car is given as

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

Substitute the known values in the above expression as

[tex]\begin{gathered} a=\frac{22-19.4}{0.65} \\ =4m/s^2 \end{gathered}[/tex]

Hence, the acceleration of the car is a = 4 m/s^2
