Answer:
[tex]a=-8.89\ m/s^2[/tex]
Explanation:
Initial velocity, u = 85 m/s
Final velocity, v = 45 m/s
Time, t = 4.5 s
We need to find the acceleration of the dragster. The rate at which the velocity of an object changes is called the acceleration of an object. It can be given by :
[tex]a=\dfrac{v-u}{t}\\\\a=\dfrac{45-85}{4.5}\\\\a=-8.89\ m/s^2[/tex]
So, the acceleration of the dragster is [tex]8.89\ m/s^2[/tex] and it is deaccelerating.
